Disclaimer: This email is written in good faith.
There is a user who is removing their own reports from the Vandalism in progress page. This user was listed yesterday for reverting a page at least 5 times. The reverting was not removing vandalism but was asserting a POV. As far as I am aware, this user should have been blocked for 24 hours, but it does not appear this happened.
By the way, this user is also a sysop, but should this make a difference? This is a serious question.
