It is my opinion that the search engines routinely change their User Agent to one that us humans use just to check for cloaking (especially if they're doing a manual review of the page). So, eventually if you're using UA cloaking you're going to "get caught" with your hands in the cookie jar. It's just a matter of time.

That is very well possible. But can't a search engine just as easily change the IP of their bot without SEOs knowing? Also, my guess is that a person doing a manual review from inside the plex has the ability to see what the bot sees. (IP based)

Also, for my situation, the cloak is only temporary in most cases.
