Different wikias have different rules, some consider any use of a second account to be sockpuppeting. Personally, I only object if it's malicious, if you are trying to fool people with two accounts or by editing logged out
You have obviously been trolling, so I don't consider the block a mistake.
Note that when you are blocked it's you who is banned - whether you are logged in or not. Not just that account I suggest you find somewhere else to be for a while, and try asking via Special:Contact for the block to be lifted after a month or so.
he's been trolling...ALOT...from going on wikis he hates and saying everyone there has autism to whenever he's blocked he'll go another wiki and tell the person to unblock him never ending! For example my friend Lebunnie...he blocked this anon and wanna know what the anon did "UNBLOCK ME PLZ I';LL NVER TROLL AGAIN"....Lebunnie was getting so annoyed
dude...you bothered the crap outta out of all of us...would you like it if you didn't have autism and someone goes on a wiki you love and someone calls you autism?...Would you like it if someone goes to another wiki and tells you to unblock them none-stop?
