There are a lot of people insulting others via pm.
Just that someone is bm'ing, insulting and harassing others by pm and others can't see that, doesn't mean that they should not get a penalty for it.
I know it would need more capacities to work on PM reports, but I think it's worth, otherwise u can actually also take away the topic reporting reasons of "harassment/spam/etc", since the people just do it via pm anyways.
I had lots of encounters with pm insults for totally unnecessary reasons already and I think the forum should do something about it in order to keep it a positive environment.
