Testbirds page
There are many surveys that prefer only English native speakers or Americans and Canadians so, I decided to give it a try. I've passed the initial test, which was 5 euros. Since August 29, I even enrolled in their "school" and solved all the tests. As for my profile, I've really done my best.
Just, during the test solving, I've noticed they offer wrong answers and, as for surveys, I haven't got any since August. If I want to get pay out, I would need 10 euros, which is a sneaky trick because, I may not get it. Ever.
In FAQ section, they even wrote that it could take months for people to get a survey. Months, are you insane? Me being me, I've sent my complain but, of course, they dismissed it, saying same things over and over again. It's really like I'm talking to robots.
You don't have to take my opinion as the wisest, I'm just warming you. I mean, I hate when there is no guarantee and only vague answers. And, to me, in this case, they are thieves. Not acknowledging and keeping the money that I've earned.
Enjoy!
