I was just curious; if you have a lot of pending referrals, will it get you in trouble/lead to any penalties?

Being able to see how many I actually have has made me paranoid. I've just thrown my link on a few different sites, so I'm not actually keeping track of who uses my link.

not really, unless it was multiple accounts being made by 1 computer etc. Basically as long as a single entity doesnt make multiple accounts that earn you multiple refferal points
