These sites have been around for years. Most of them are bullshit.
There are some sites out there that will pay you ped for doing various tasks and stuff. Entropiapartners is one site that actually has been around for years now and does pay people. Other sites like ped2click or whatever it was, was a ripoff and scammed folks in the long run. There are a few others like that still out there also.
Do not EVER send money to these sites. Do not EVER believe the bullshit THEY post on their site how wonderful, reliable etc they are, they are trying to lure you in, and Id strongly recommend not EVER using a referral link the ass wipes constantly spam chat with to join these sites under them.
If the site was really that wonderful, they wouldn't need to be spamming it, word would already be out and people would be beating a path to it.
ALSO, EU has a pretty tight EULA. poker, roulette, etc are all forms of GAMBLING, no matter what you want to call it. Gambling is illegal in many countries, is highly regulated etc. You are just asking to get your account suspended or worse if you mess with this stuff and EU finds out. They have NO problems seizing any and all property you may own, auction it off and keeping it if you violate their license badly enough.
Oh and double finally. even something as simple as, Person A saying I will give you 10k ped if you pal pal me XXX is against the rules. If you get ripped off, you have no recourse, and complaining to MA will get you locked out because you intentionally broke that rule.
You have money, others want it, and will go to any means to get it. Be Warned, Be Smart.
