It seems we have a new user who likes to leave comments, a tad on the aggressive side :

I flagged a handful of them, but I'd rather raise the issue here once than go after them all, and there are many judgement calls to make between "too rude" and "kinda acceptable".

e.g. thread getting (imho) slightly out of hand :
