It recently came to staff attention that MKhalael, now KhalM (account age 5 days) recently downvoted over 100 pages, most of them on the top-rated pages list. Their sccper record indicates that they seemed to have targeted specific authors as well: http://www.scpper.com/user/7281009
Given that the only two upvotes they have on record are 914 and their own article: http://scp-wiki.wikidot.com/scp-5181 (where they left a comment
http://scp-wiki.wikidot.com/forum/t-14009744/scp-5181#post-4907127 that mentioned "Rating kept going down and I had no idea why because nobody was saying anything." and later http://scp-wiki.wikidot.com/scp-5181/comments/show#post-4907204 "I got greenlight on the concept but I have to admit I skipped the draft review because some users said it wasn't really necessary, now I see that took it's toll in the final result." they have no forum activity so no greenlights can be confirmed there) this seems like a clear case of malicious downvoting.

Recommending ban.
