I mentioned elsewhere but here's a copy and paste:

It is far more than just that. Removing comments is one thing, mass-banning from many communities at once despite never even having commented in them at all is another, but the real issue is using database manipulation to delete the log entries as to why the comments were removed after the fact.

Even if unintentional, which strains credulity, this is some spez-level stuff going on, where we have the option to either take what a single person (who does not seem inclined to follow their own stated rules) offers, or else we can leave. Many are choosing the latter, and like the Rexodus, making the situation known to others as well in the process.

“Criticizing China” was merely the spark that lit the match, with the situation offering proof of what apparently people have been suspecting for some time now.
