Is it a scam? Yes or no, I’ll explain what actually happens inside it.
A good proof for PTC websites is having a forum, neobux does; but it’s strictly under control of administrators, so any complaints or negative reactions will be removed and user will be banned from forum permanently.
What about referral packages? Oh boy.. They won’t last long. Number of clicks will reduce over time and most of times total clicks won’t reach 100 and you’ll need to renew them and it costs.

I’ll say it’s a smart scam, I didn’t earn profit after 1 year and that’s a proof.
Only real referral will give you money and it doesn’t worth of it for small money
