There's recently been a spate of extensive vandalism to high-use transcluded templates - the other night I dealt with dozens of OTRS complaints which could be traced back to someone (or multiple someones) vandalising {{cquote}}, {{otheruses}} & {{taxobox}} in the same manner. I've seen this form of vandalism before ({{bio-stub}} is the one I recall...), but rarely to the same extent - any particular vandal incident is rare if it generates two or three seperate complaint emails, and there were bucketfuls here.
I've seen protection for high-profile templates like this mentioned before, but never implemented; after I mentioned these attacks on WP:AN, someone protected all three. Is anyone capable of coming up with a list of all individual templates transcluded on, say, more than a couple of hundred pages? Even if we don't *protect* these (I strongly suggest we do - they mostly shouldn't be edited without a good reason, much like the MediaWiki messages), having a few dozen admins watchlisting them would be helpful.
