Wapchan uses an automated moderator affectionately known as "Ranbot".
First and foremost, Ranbot cleans up CSAM and other forms of link spam. She isn't perfect, but she does a fairly good job. To ensure you don't get flagged as a spammer, don't use pastebin clones (the original is ok) since these are routinely used by spammers to post CSAM links.
Ranbot also edits the text of posts who use what we consider derogatory/spammy language. Please do not try to bypass this unless you are posting a link (abuse will result in manual bans). Affected words are listed below:
fag -> fren
faggot -> friend
Any form of "nigga" -> neighbor
troon -> raccoon
tranny -> granny
There are also words filtered for site culture reasons:
