I can post whatever I want in ingame messages, but not in PMs.
I can post whatever I like in private clan forums, but not in the general forums.
Robomod checking my posts in general forums I have no problem with, but I think we should be able to write whatever we like in PMs.
We have ignore lists, so people can't easily harass any person using that channel, why can't I write whatever I feel like in PMs without robomod looking over my shoulder, going 'tsk tsk - watch your language boy!'.
One solution I see is having a personal setting I can use to say if I need my PMs filtered.
