I'll assume you were on Peanut Labs. Some do have suspiciously long and varied "screen outs." Whenever I get one of these, I report it to PL using Other. (Under transactions, the top offer will be your last, and therefore the culprit.) I tell PL that I don't expect credits, but am just reporting the suspicious behavior.
I seldom hear back from them, but I've noticed that a few that I've reported quit showing up.
It feels good to vent, but it feels even better to do something about it.
