No unlawful or objectionable content: unlawful, harassing, defamatory, abusive, threatening, harmful, obscene, profane, discussion about users who have a terms of service violation ban, sexually oriented, racially offensive or otherwise objectionable material is not acceptable.
Bans don't really concern those who are not affected by them (I.E Everyone other then the person who was banned). As Slapy47 pointed out we generally remove the posts that got the user banned.
