Because you have already been blocked three times prior and haven't shown even the slightest interest in changing your behaviour since you got back from your previous blocks, you have been placed on an indefinite block.
You may be allowed to request to have this block shortened or lifted, once you have understood the reasons for your block and have agreed to stop doing the things that resulted in your block.
However I can honestly say that for what it's worth, after the nonconstructive behaviour that you have shown, the chances of you getting unblocked are very slim. So if you genuinely want to edit constructively, I'd advise you to plead your case very carefully.
Because if you abuse this privilege of appealing an unblock, you will have your message wall access revoked. And if that happens, you won't be given another chance to return to the wiki.
