I think we all understand that, in principle, one can with one's self-moderated thread do what one wants, but to suddenly delete many where there has been significant discussion and quite a lot of merit, just smells bad. Like wanting to erase evidence, as has been commented.

I wondered in the previous comment to this thread if Ratimov was going to come here to explain himself but it doesn't look like it at this point. Not the behaviour one would expect from someone who is 100 most trusted, 4 most merited etc according to bpip.org.
