There is a certain user I've seen answering some questions on SU that are... well, just bad. Most of his answers consist of a few more questions to the poster (that should be in the comments) and then a wall of text.
Most of his answers contain things like "Voila!", "Blamo!", "This will help!", and other Batman-esque catch phrases, followed by some gloating about how he's somehow helped the OP by saving them money and such.
Really, the answers aren't that great - content-wise, formatting-wise, etc. I guess with a lot of editing (time), they could be passable. However, he's been a member for 6 days as of this writing and already has 26 answers, most of which are as bad as the last.
What do you do in this situation?
