It's certainly true that you speak your mind and you have in recent times verbally abused a few people I can think of - and probably a lot more people over the years.
Having said that, my guess is that nobody at BCG (including the management) sees you as a nasty or disruptive person. My guess is that even the people you occasionally insult see you as a bit of a character rather than somebody they actually dislike.
Unless I'm much mistaken, the people you've verbally abused recently are intelligent people with a good deal of life experience. I suspect that over the course of their lifetimes to date, they've been called much worse things than you've ever called them.
Accordingly, they haven't complained to the site management and because (if I'm correct) the site management see your abusive posts as "characterful" rather than a threat to the health and happiness of the site, they've seen no need to message you about your occasional excesses.
Personally, I say keep it up!
