yeah 2 years - it's a big scam. You'll only get paid if you pay for premium referrers.
PTC is crap - but I'm testing a method for neobux right now. Not investing any money, just doing the daily 4 clicks and leaving quickly. Making it a routine with a few other methods I'm trying. All about experimenting and seeing how it goes. With neobux, the idea is a bit more nefarious - don't intend to use it for ptc hehe.
