I am a dentistry student. I generate income from my account to meet my university needs. This is my only source of income.
How the fcuk did you get into dental school if the only source of income you have is through bounties? I don't know how it works in your country, but where I live you have to have paid for each semester or year in advance before you can even start studying dentistry. I have to assume you got loans to finance your education.
I do not want to defend him here. As I commented in the other unban appeal thread, he would come to be paid in the signature campaign about $45/week. He writes in Turkish, so maybe that money is enough to buy food or partially cover his expenses, and, assuming what he says is true, I suppose, as you say, that he took a loan to pay for his studies.
In any case, it sounds to me that he says it to make people feel sorry for him. If he is studying that he has a promising future and while he is studying he can look for a living to get income either online or live. This is not the only possibility in the world that he has to earn a little money.
