It's a good site, I can confirm as I got my second payment a few days ago but sometimes there are problems with the login/logout. Sometimes it kicks me off and even if I login again, after the fist few clicks I'm automatically out. I have reported this before.
The surveys are a bit problematic, I finished two the other day and I got my reward only for the first one, the second time that it happens. Registered also for some Russian dating site but got no reward for it either
... if my wife finds out about it, idk how i'm gonna explain it;).
Anyway, for me the overall rating of the site is high. I enjoyed my time making my satoshi there. It's understandable that there gonna be some things to be fixed but that's the point here, to test it,find errors and promote it.
Good luck to the OP with this project
