WTH is going on with Yoursurvey ?

Yesterday I over 200 surveys rejected even expired ones and my quality score went to -150 points from 450 quality points and now I have over 32k quality points all of a sudden: https://imgur.com/a/2zwbWsV.

I noticed several people got tons of survey rejected on yoursurvey and got told by support that the rejections are legit, even though it sounds fishy that someone would reject over 150 expired surveys in less than 1 hour manually.
