It depends! Normally it’d take a week or so, but if it’s a confession about a character that has gotten a lot of confessions within the span of a week or so, it might take a while.
If your confession isn’t published after a month, then it’s likely Tumblr ate it or we didn’t accept it because it broke our rules or there was a similar confession posted already.
