the reason I wanted to be a moderator on my own thread was after I read that it turns out that I can moderate my own posts in a thread on the board. then I remember seeing a thread where the reply post was completely unrelated to the topic being discussed. and there the avenger even promotes a website. but now the reply may be gone because the moderator has deleted it. although the existence of the reply post is a bit long.
You can quicken the deletion of such off-topic replies by reporting them to the moderator as soon as possible. The report button is usually at the bottom right of each post.
although I'm not sure when to use this feature. but maybe one day when I make a serious discussion topic this is what I really need.
It's usually good when creating a discussion topic in boards where there's too much spam
