I asked them what type of block did they issue but knowing them, I doubt they issued a block of the IP because they aren't willing to get "personal". Also, VSTF issued a ranged IP block the last time and he returned before the block ended therefore even if Fandom issued a global block on him he would be able to return after changing IP.
Damn. But at least he has one less IP to use. I will continue to flag him every time he does severe vandalism, hopefully Fandom will end up globally blocking all of his IPs. He is not the only one good at the stubborn game.
