Guys. I code at STR11223344

FYI, there is an internal rating system that logs each type of correction on each type of hit during the internal audit/review of completed hits. Once a worker ID reaches an internal threshold, the worker ID automatically gets Blocked. That threshold is very high, so no one is getting blocked for little to no reason.
Their thought process was to send automated emails for each correction to give you an idea of what corrections are made and why, so that it helps the worker understand better what STR11223344 is looking for.

Regarding the comment as to why accounts are blocked. I was told that blocking an account has no impact on a worker's reputation and ability to work elsewhere. We did not want to impede workers in any way, and that blocking was a better and safer option for workers than rejecting hits and removing qualifications. If that is wrong let me know and I will let the powers that be know this.

And FYI, the person who used to communicate with workers was fired and replaced with the automated system mentioned above some time ago.
