If you have an issue with an admin...I'm sorry, but you're own your own.
Advice? Just take their verbal insults, accept they are right (even if they aren't), their behavior will receive zero consequences, and just walk away. There is no point fighting it.
You will be blocked, told you are wrong, and they treated like they are royality and told they are right. They are basically the police department of Wikipedia, except you can't defund this one.
Not all admins are bastards (Mlaffs and Wehwalt are proof of that), but the vast majority are. They let power go right to their heads.
When one is called out, the others flock down and defend their brethern, pelting the brave soul with insults and threats, consoling their friend with "you're right" all at once like the seagulls from Finding Nemo.
Finally in one big circle jerk, they band together in one anapomorphic being and slam the brave soul down, or block them, and celebrate their comrade having vanquished another foe from sullying their name with their truths (how dare they speak truth!) and "receipts" (which are promptly RevDel'd, because we can't have evidence).
Nevermore will that brave user be able to edit where the keyboard warriors edit. Not knowing that they, themselves, are mocked on other sites (like Reddit) and are nothing more than the "Karens" and bullies of Wikipedia, responsible for this sites ultimate downfall.
At least the truth will never prevail!
Things That Should Go Without Saying
Trolls: If you are here to bitch, whine, moan, or complain, consult an admin. I honestly just do not care what it's about.
Admins: If you are here to bitch, whine, moan, or complain, just block me and get it over with. I ain't arguing with you, nor am I fighting the block. You're gonna do what you want, consequence free anyway. Have at it.
