I'd like to say that I have been using instant-btc.eu for quite some time and even though almost everyone has called them a scam, I have been paid out quite a bit from them. It's strange because it's actually one of the higher paying faucets I've found but it's just extremely inconsistent and you never know when you are going to get paid.  This is actually the longest stretch in which I haven't been paid (maybe 2 weeks), and maybe it is in fact a scam. BUT I have been paid out from them 10-20 times at least so it's hard to know for sure.
