All purely political topics should be moved to Politics & Society, even if the discussion doesn't really concern politics moreso the society at all. At least, it keeps everything organized in a forum sense.
As for the signature campaign, it would be best to leave it there. It's up to the nut jobs to join the campaign if they'd like to. If their comments on certain topics become directed towards personally attacking someone, one can always report them and they'd be dealt directly.
I don’t think personal attacks require moderation. Can you please post the related forum rule?
We don’t post in a communist forum where people have no freedom of speech as far as I know.
Hurling insults towards another person instead of discussing the topic at hand is, IMO, spamming. It may not be a severe violation of the forum rules but, it falls under 3 forum rules:
1. No zero or low value, pointless or uninteresting posts or threads. [1][e]
2. No off-topic posts.
3. No trolling.
Idk about you, but if a topic is about X and some posts are about why OP is bad because of attacks completely unrelated to the topic, those comments should be moderated.
Of course, not all posts with a hint ot personal attack
should be moderated, but only those who are outright ignoring the topic at hand just to get their insults across.
