How to remove your Wikia account
You cannot remove your account, due to “certain limitations”. However, there still is a lot you *can* do, which is listed on this site: https://help.wikia.com/wiki/Help:Closing_an_account – so Wikia gets a grey listing here.
To contact them, you can use this form: https://community.wikia.com/wiki/Special:Contact/general
Helpful Trick: Removing online data
Publicly visible text/images often aren’t properly removed even when you succeed in removing an account. Try editing or removing them manually before removing the account itself. If you’re unsure what happens to your tracks: this can be found mostly in the Terms of Service/Privacy Policy; otherwise you can always contact Wikia and ask personally. By the way, removal requests don’t necessarily mean your data will actually be removed (e.g. due to legal obligations).

If you signed up for Wikia using a third-party login such as Facebook or Twitter, you probably want to revoke all access from Wikia. Click here to find out how.
