I processed a lot of the reports, and removed the threads, not just from this user though there was several others reported at the time, and not just this user. Probably handled 100-200 of the reports. However, I only removed those that did not have any replies at all, had not trust references directed towards the thread itself, i.e one's which basically offered no value whatsoever. I left some in the queue towards the end of the night, due to needing to attend to some real life things as well as further investigation on a few which had trust ratings which I would've looked at later if they were still in the queue.
Having said that, I wasn't the one to mark any of the reports bad. In fact, I left the one's which did have replies as a soft bad, by just leaving them unhandled, because I can see it from both points of view. The global moderator who handled these reports, must have thought they could've been significant to the history of the user, in some way I imagine.
Generally, we don't allow users to remove their own threads, and I guess this could potentially be abused, and whoever marked them bad could be thinking along those lines. However for me, since there was no replies or any trust references/flags left, I thought they were insignificant enough to be removed. Maybe, whoever handled them had a different point of view to that.
As for deleted topics containing user responses, I completely agree. I do not touch such topics, because I know that with a high probability, this will be BAD. I've been reporting mainly to empty threads that don't contain a single post or contain a single post that is garbage and doesn't make any sense. Today, no one began to delete even empty topics, they were simply transferred to the archive. I know this is normal practice for very old threads like 2014 or 2015 but these are empty threads from 2018. What is their value?
Until today, I could 100% answer YES if someone asked me, as an experienced reporter, if this could be considered low-quality posts to send a report:
Vv
Delete
***EDITED***
And now I will say that I do not know, maybe these are quality posts. Now Im not at all sure of anything here, and everything that happens more and more reminds me of some kind of random.
