I have accidentally discovered the website viespar.ro and it looks promising so far. The idea is plain an simple, you subscribe then you get different tasks you should complete (like searching for some keywords on google, visiting different web sites or facebook pages and so on). Once a task is completed, it requires around 7 days to be manually verified then the payment (which is usually between $0,10 and $0,20 / task) is credited to your account. They also have a referral option which looks pretty much as a standard MLM system.
The sign-up bonus is $5 which are immediately credited to your account as soon as you signup and confirm your account. I don’t know yet what’s the minimum amount of cash you need to have in order to withdraw.
