Recently, a user has been spamming the category "Episodes featuring Doctor Weird" or something similar. The community has already come to a consensus that we weren't going to put this category into use, yet the user continues to spam this category every few days.
Though we do get a lot of positive contributors from IP addresses, we also get a lot of spam from them as well. Blocking them isn't an efficient way to deal with them because it's a simple task to change your IP Address and continue posting garbage.
So my question to this community is as follows: Is it worth asking Wikia to disable editing from unregistered users? Should we expect someone to make an account to edit in order to get rid of the vast majority of vandalism that our small Wiki receives?
