One thing I've noticed a lot from the Indonesian users is they tend to claim to be female in the profiles as well.
I think that this may be due to the idea that females get more attention on the internet than males, maybe hoping that they would receive tips from other forum users because they are female.
Although I have the feeling that users are not spending their signature campaign BTC to gamble, although I could be wrong. This is somewhat evidenced by the lack of loan requests in the lending section of advances of their signature campaign earnings.
I wouldn't be too sure, back when I used to gamble a decent amount of it came from my signature campaign earnings. It wouldn't surprise me at all if signature campaign earnings were used to gamble. Whilst you said, I couldn't see it being extremely likely that a minor would do this, but there are obviously exceptions.
Also, this seems the best place to ask for now, do you see my posts as low quality? I've seen a lot of posts complaining about low quality signature campaign spammers, I would like to know if I was in this bracket.
