I was in the cult for a few years and I did come and go as I pleased and kept aloof from the group as much as possible but at 16 I was told that there was a devotee who was assigned specifically to look out for me and all the other younger students without parents. There was a disciple assigned to accept money on Siddha's behalf that every body knew about.
Devotees are not rewarded per se and from my experience there is not a recruitment drive and a lot of newer people do not stay long. Some of the disciples run advertisements for meditation classes. There were younger people that I knew of who went to Hawaii and engaged in door to door preaching but there was none of that going on where I was even when Siddha was in Australia for a whole year. A lot like you say are down-trodden and often very lonely.
The indoctrination is that one needs a guru. Without a guru you cannot know the highest happiness and get off the wheel of birth, death and suffering.
If you are involved in the group and wish to engage in some work like preaching from your home or anything else you may find will be helpful to others you will be told by disciples that any activities should be approved by siddha first. So you write Siddha a letter and you shouldn't expect to get a response. The only choice you then have is to travel to Hawaii and try to obtain a service job from him.
Otherwise you may work and it is suggested by Siddha that 50% (he must have lowered his standards since according to Cara) of your money be offered to Krishna as it is not really your money, it belongs to God and God gave you that money. Alternatively Siddha suggests that devotees only take what they need to survive and give the rest to Krishna. Of course since Krishna is not present offering it to Siddha is the next best thing. If you do work it doesn't matter on the job as your service to guru becomes giving him money although you will be highly criticised and looked down upon if you work anywhere that contributes selling of any kind of meat. Same if you live with another person that eats meat. If you wash your clothes at a meat eating person's (or demons as they are endearingly titled) house you will be highly criticised. Same with a homosexual. Talking to ISKCON people, eating their food or listening to their singing is contaminating you. Avoiding society altogether is a good idea.
Food is difficult and yes it is taught that too much sleep or food is not conducive to spiritual life. SoI are highly fanatical about food and I was even given a list of food additives that "may" contain animal products and they are highly against any processed foods anyway. So you find that it is very hard to eat so you begin to eat the most simple foods as you can. Also enjoyment of food is taught to be a way of enslaving you to the material world. There was a story of a devotee in India who only ate raw rice out of a human skull so that he would always be aware of his oncoming death and that he would never become attached to the taste of well cooked food. It is regularly stated that Bhaktivedanta slept for 4 hours a day so you get the sense that sleeping as little as possible is the best way to go.
It is taught that your mind is imperfect therefore engaging in mental speculation (or thinking) is a futile practice. It is also said that idle chatter is worse than death and when you speak it should only be either purposeful or about Krishna and guru.
Siddha can turn a discussion about a lovely, duck-filled pond into a rant about death, sexual perversion and homosexuality. His three favourite subjects and fear of leaving is probably the strongest tactic used. And guilt as you say as the opportunity to meet a pure devotee only comes along once in thousands of lifetimes. So you are taught that you are in a highly privilleged position that is an extremely unitelligent to throw away. Siddha's teaching of how undesirable the lives of regular people in society are means that you also begin to feel guilt and distaste for a normal existence. This is then affirmed as proof that a life outside world is tasteless. But really it is mostly tasteless because that is what you are repeated told.
It is taught that without guru you are merely a walking corpse about to die at any moment. He constantly talks about the urgency to quit suffering in this material world and he goes to great lengths to explain the most extremely unpleasant things about this world.
This is the ideal of siddha's mission if you are able to give up your whole life for Siddha having a job where you give him all your money have children that you will bring up to be Krishna conscious and you spend 2-3 hours chanting on beads with an hour or so of morning and nightly offerings to Krishna, listening to a forty minute lecture of Siddha's and some include a reading from the Bhagavad gita and if you can give up all attraction any enjoyment in this material world of food, sex and not paying attention to the media or television then you have achieved perfection in this life. Otherwise you should be striving for the above and you will be eternally happy...
or so the story goes...
By the end you are so starved of friendship and enjoyment in life yet you are so extremely scared to leave that you will be condemning yourself to death. You come to believe you really need this guru or life is completely meaningless. As you can see from this thread the guy is just an arrogant, well-off, paranoid, neurotic and not worth the chair he sits on.
I think control in keeping you involved in the cult occurs more for those as Cara described who are caught completely and those who are of certain material value. Others they not overly concerned about.
The reason I left was that it was great in the beginning and you do feel like you have found a real home but after a while as you become more and more isolated from society the lonliness and misery begins to set in. Also many of the so called truths like that the moon is further from the sun made me question as this is clearly not the case. The behavior of the guru makes you begin to wonder as you do expect a person in this position to not act so childishly and uncompassionately. Finally I was too lazy to sit there bored for two hours everyday doing my rounds. You just sit there saying to God "Isn't there something more productive I could be doing than this?"
Oh and he told a story how he grew up not knowing he was a white guy. i figured he is either lying, exaggerating or completely nuts.
Oh and here's a few quotes from the person they call the guru of the entire universe:
On Abortion being murder:
"Everybody also knows that there's prejudice against the blacks. The blacks aren't happy in that sense. Black people are unwanted." ..."Should they have killed the Chinese people? Yes, if they accept the theory that unwanted persons should be killed."
"People will start suggesting that we should become homosexuals to solve the population problem. I am just waiting for the Planned Parenthood Association to back up homosexuality as the practical solution to overpopulation. They might even teach it in schools."
"And maybe, if [a bisexual] becomes more free, he will come to the point of having sex even with pigs and dogs." ..."This is actually going on in the United States and Europe."
"IF YOU ARE A CELIBATE IN SAN FRANCISCO, THEY THINK YOU ARE STRANGE, BUT IF YOU HAVE SEX WITH A FIRE HYDRANT, THEY THINK YOU ARE ALL RIGHT."

Here's one for Private eye on giving presents on christmas:
"Now Christmas is supposed to be the celebration of Jesus' appearance day. So these people who use this day of all days to teach love for mammon, must be seen as the anti-Christs."
