Has anyone been banned from Qmee?

There's another survey site I use where people are banned for no reason and aren't paid for the money they've already accumulated but not cashed out, but with Qmee I've never seen a post on here complaining about it (maybe people have been banned but just don't give a shit). I've failed attention checks but it just ends the survey there and then and nothing else is mentioned of it.

Do people actually get banned from this?
