On Wii Sports Wiki, a user named Blaze Bro. was inserting false information and harassing me. I blocked him, but he created a second account called MamaKrabs86 and did the exact same thing. I blocked him again, but I know that he's just going to create more accounts and screw up the wiki even more. WHAT DO I DO?

(any suggestions would be great)
