In a nutshell, try to find out why the admin blocked you. If it was in bad faith, try to contact them on a neutral ground like their CC message wall. Wikis should now have a well-defined rules article, and if you feel the block was arbitrary or not covered within the framerwork of the wiki's rules, you can contact Fandom staff. Don't start harassing the admin though.
Pardon me? Drama king? It is you that inflicts drama. I attempt to peacefully communicate with you, merely for you to inflict drama, and then I simply continue to participate, however, then again, it occurs every once in a while. So no, I am no "drama king", as you state.
The user who banned you is blocked across all the fandoms. To get unbanned, please write to another admin, or to fandom, telling them, that you have been blocked for no reason, give proof, and mention that the person who blocked you, is now globally blocked form fandom.
