Forum:I.P. user repeatedly spams wikia

Hi, I am having a problem on the Once Upon A Time wikia (onceuponatime.wikia.com) of which I am one of the administrators of. I blocked a certain i.p. user who was behaving very badly against other users in the comment sections of some pages. The block was permanent. He/she was under the i.p. address starting with 76. He/she came back under the i.p. with the beginning numbers 67. I blocked, and the person came back under the i.p. beginning with 77. This person has threatened me ever since I blocked him/her the first time. Please help me with this. I don't know what to do. Applegirl (talk) 01:28, November 12, 2012 (UTC)
