Today I opened my watchlist and a strange entry appeared.
10:07 (Protection log) . . Gilliam (talk | contribs | block) (log details removed) (Persistent vandalism)
I found it odd that the protection log details would be revdel'd so I investigated. It seems the edit was revdel'd, but not the log event. The watchlist portrays the log event as being hidden and that should not be the case.
