The cheat he was caught using was getting all of the achievements for his games, even the online ones, offline and out of order (for example getting the 1000 kills achievement before the 500 one) and then activating them. This is a clear indication of cheating and there is no chance of false positives here. All he did is pay someone online to do it for him, and his mom has said she knew about this and didn't consider it cheating.
2) I do not have a twitter account, but it says I am logged in (and its blocked by Websense).
He tests if you CAN'T access a page to test for twitter (logged-in users can't access the page but non-logged in users can), which is a problem if it's blocked for other reasons.
