Vandalism is absolutely not the way to do it, and will completely hurt any cause you had. If you were genuinely interested in that I would suggest contacting an administrator and making a case for why you should not be blocked, but after repeated attempts of vandalism I would be surprised if they give you your account back.
If your actions when you have an account is to repeatedly vandalise and blank out our pages I can't say that I blame them. If you are genuinely interested in receiving your account back and working to make positive, helpful changes then you should first demonstrate your interests in doing such and work towards that. As it currently stands, all you seem to have any interest in doing is vandalizing pages, so you have no compelling argument for having your account back.
