have you wrote a post that was aggressive and written with profanity? or anything controversial? The problem is they nuke the post with downvotes then it becomes buried and how would you know about it :/ 2 of my posts this has happened too because i write aggressively sometimes. (Which it is my right to do so here) its the profanities that got the post downvoted but regardless.....

I understand. Don't let it bug you.
Work to change it from within, keep it stealthy.
In other words, better kept covert not overt.
