How can I obfuscate my writing style when I review papers? Does anyone have any good advice for obfuscating one's writing style when reviewing papers?  I have a fear that I would inadvertently use the same turn of phrase in a referee report as in some published work, thus revealing my identity, and I'm curious if there is a good general practice to follow to mitigate this as much as possible.
It's not worth it. Few waste time trying to unblind their reviewers to take retribution for bad reviews. It's just not worth it. The average journal submitter doesn't have enough power to do damage to a random reviewer. 

If you need a strategy, trying passing your text through Google Translate to Spanish and back to English. It'll probably be garbage afterwards, but it'll definitely lose any idiomatic turns of phrase that might identify you.
