It's a known fact that, when doing a just-ask giveaway, most of the invitees will get disabled for inactivity or low ratio.
But how do some of them manage to get their accounts disabled after 2 hours? My record is 24 hours. Do they go straight to the IRC and start start spamming porn sites or what?

Just happened to me yesterday.

Sucks to be true but some people probably have low IQ or no IQ at all...

Yeah... I agree with you.

One time I invited a guy whose account was banned in.........30 minutes!!!

I said him: How can you be so st**id??? and he answered. Sorry

Yes, I know how it sounds. I was a "victim" of that few times.

I'll answer that: when they use the same nick here as on the tracker or they start cheating right away.

Or maybe their IP address had been used before?
