It's been 5+ min and I still can't delete a comment. There is no other forum which have ever existed which makes you wait to DELETE a comment.

After 9 minutes I was finally able to delete.

You can delete it immediately if you post again.
It's useful for fixing an error, just copy the post, fix stuff and repost and delete the original, no timer.
Works best on slow boards though.

They call me the 4chan ghost on some boards. I only make sure I have one post up at a time, and delete the previous if I want to make a new post.

Reduces my carbon footprint significantly.
