We aren’t going to go full in depth of everything we do, but generally we edit if it’s against the rules.
Two main ones I usually have to edit is if people put their personal IM information in a post, which I will also leave a mod comment or reply mentioning that rule.
Second one is post padding. If you post multiple replies in a row, will condense to one reply but all the replies are still intact.
If a conversation is too against the rules, then it’ll just be deleted.
