WikiWeasel

A WikiWeasel is a troper that rather opinionated and often hangs around pages where YMMV items are being discussed or trope and adds their two cents.

They can be very helpful, especially those who are aware of what is considered YMMV, and they often are able to sort out what is blatantly untrue from the actual differences in opinion on most topics. However, they can be annoyance to some WikiFauna when they edit pages where objectivity is preferred, even if their edits are in good faith.
