That's not a bug, and it should remain as it is. This website is a wiki, and that is true even though this is a forum. Anyone is able to edit anything on a discussion page. If someone posts something in the wrong place or even literally spams, then anyone can delete it, and it's perfectly normal. We shouldn't restrict this, but, of course, if someone abuses it, then we should do something about it.

It isn't a bug and it is even intended to work that way.
