weew lordy thats a lot of words
Nobody needs to read all that (nor should they) to know that

In your whole rant you only mention QS's name 1 time; your whole thing barely even counts as "on topic" discussion.
I for one think the plagiabot (j/k I know its not a bot but thats a fun name for the process) goes back a bit too far sometimes, but in general it sure is a stern reminder for shitposters that copy/pasting doesn't pay. Anybody who would be outright against such a thing has personally motivated reasons for being so. The fact that a few DT1s have been caught and banned recently is pretty solid evidence of its impartiality.
Accounts that have proved their worth over the years since their last offense have indeed been re-instated, though sometimes with a penalty, so I don't understand the arguments against these recent wave-bannings.
