Not that hard if you are talking about banning a user.. .you can already do it directly by clicking on their name on the post itself that they made, have their "blurb" kick up and then click on the moderator tools gear in the upper right hand corner.

That way, you don't "accidentally" click on something on someones post and it end up banning them. Takes a few more clicks, but it fits better into the moderator tools honestly.
