A shared writing style, including the use of characteristic idioms, spelling mistakes and punctuation foibles, is often a dead giveaway in these cases. It's hard to consistently disguise one's writing style over a long period of time without serious effort. This is best spotted by the experienced human eye -- at the moment, there's no automated support for this kind of analysis in MediaWiki.
There were some interesting studies that found that a machine learning based system could distinguish male from female authors based solely on the writing style. Maybe this would be a good SoC project for a computer science student?
