You are listed as the "deletion user" in the moderator view of the comments, so apparently it was your flags that did it. However, I don't know what reputation endows this "super-flag" ability.
Deleted comments from the second question:
Theo: Voting to close as not a real question. http://en.wikipedia.org/wiki/Fermat's_Last_Theorem
Theo: See also: http://www.simonsingh.net/books/fermats-last-theorem/
Theo: @Brian: I'm having a hard time believing this is real. How does one come up with one of the most famous questions in mathematics and be unable to parse the eminently readable first paragraph of the wikipedia article?
dsadsa: Theo you are a shining example of math elitist. Spouting about your bulls*** of simple concepts and ideas of math and how only a complete idiot wouldn't understand what a modularity theorem is. Well f*** you, I am so sick of elitist f***s like you. I work so f***ing hard at math, but it just doesn't come easy to me like it does for you.
dsadsa: Actually I am not done, I can't stand pieces of s*** like you Theo. You were probably picked on a lot as a kid so now hiding behind the internet you can say whatever you want. It is pathetic, and you are just as bad as them.
