That depends on the circumstances. If you were blocked sitewide by a staff member or VSTF, you have no chance of ever getting unblocked. If you're a normal user who was blocked from your wiki for misbehavior, you can likely still ask to be unblocked on your own talk page or Message Wall. If you are an admin and accidentally blocked yourself, you should use Special:Contact to request staff help.
unblock yourself from what? so need to write more
you can't.
How do I unblock my browser? I can't access the internet even though my service provider verifies my internet connection. What do I do?
No you can't
Unless you blocked yourself in the first place (in which case, do that, but opposite), you don't.
wikipedia
You can't unblock yourself. They have to unblock you by going to your page and hitting "unblock friend" It should be right where it usually says "Block Friend" If they just un-friended you then try re-adding them. If they don't unblock/re-add you they obviously just don't want to be your Facebook friend anymore.
Wikia's population is 127.
Wikia was created in 2004.
You don't have to be an adult to have a wikia... But you have to take your wikia site seriously.
Wikia is owned and operated by Wikia, Inc. So, since they're both Wikia, I guess you could say that.
You cant unblock yourself if they blocked you but if you blocked someone you can unblock them by going to your account then settings, in the settings you will find block users, click on edit then ull know the rest :)
