There was a recent post in the "how to report bad behavior" thread where somebody asked how to blacklist racist words, which is what reminded me to make this thread.
Apart from that I know a few people dislike certain words in posts, such as "faggot", which they'd rather blacklist but are unable to with E6 not tagging words.
A bit ago I downloaded all the posts on E6 and ran them through OCR software, which would make tagging specific words easy with my bot, so it wouldn't take too much effort going through old posts to fill out the tags.
I was thinking we could tag generally offensive words with x_(word) and possibly make a new tagging category for them. Obviously the more awkward part would be deciding what words count as "generally offensive" to tag, as we wouldn't want to tag every word in a post.
I just thought it could help people blacklist more content that they dislike, and help people who like that kind of language to find it easier.
