Since Fandom blocked your account globally, then you must've broken the ToU as they don't globally block users for no reason. Using alternate accounts to bypass them will only increase the length of your global block.
Since posting here in Discussions isn't going help you a lot and we can't do anything about it, you should contact Fandom Staff.
In all honesty, your account will be blocked again. But in order to get a less lengthy block, make this your last account and don’t make another sockpuppet. Contact Fandom staff for any questions you would like to pose them.
