It's only fair to see this in the proper context, although I will, unfortunately, have to extrapolate from anecdotes and subjective interpretations.
The consistent "theme" with the recent unending string of dramas on SE is that they create an impression that at least SE doesn't care about the community, if not worse (repeated soulless and/or inaccurate statements about Monica, massive resistance against community input on the CoC, consistent negative comments about the community in blog posts, firing of Community Managers, etc).
That impression in turn leads to people like me not seeking to be banned, but not caring if I get banned or not either. Want to ban me? Sure, go ahead. So I don't have any incentive to limit myself.
In summary, it seems only logical that if more people don't care about getting banned, more people will be banned.
What got me 1-week banned was protesting, by repeatedly describing the events in detail, Robert Harvey's 1-year ban for civilly proposing an alternative CoC. Don't bother looking for it, the question about the alternative CoC is gone, as is the thread about the deletion of that question, and the question about the deletion of the question about the deletion of that question. Some people posting in those threads have been banned too, although I can't say for sure why that is.
