On the Disney wikia, on a page for a certain character, a user made a bunch of edits. I don't believe her intent was malicious or anything, but she added a lot of info that was incorrect or didn't belong in the article. I removed these things and also fixed a spelling error. These were very recent edits, made today, and removing them did not damage the page at all.
Another user undid my edit, with no explanation. I undid that, asking her to post on my Talk page if she had a problem with one of my edits, instead of just reverting it. Then I saw she was an admin, so I posted on her talk page, explaining why I'd removed each thing that I did. Withing seconds, she had removed my message and undid my edit to the article again. This is pretty poor form on its own.
I entered into the Chat with her, and was utterly appalled. I told her I was upset and asked for an explanation. She ignored me for a while, before answering me only to say I was rude. Suffice it to say, things eventually got worse. She insulted editors in general, saying she didn't have to respect us, because we were a dime a dozen. She protected the page, then edited it to placate me, except her edits did not have anything at all to do with the problems I had pointed out. She even falsely claimed I was blanking the page, when I only removed a few things that had only just been added. And if they are wrong, shouldn't they be removed? That article now contains a lot of false info, and you know how it is when false info gets out there-it spreads like crazy.
This girl is an adult, and her behavior was truly apalling. I honestly was effected very badly by the way she treated me. I'm not sure what I hope to accomplish by posting this here, but at the very least, it's nice to tell someone about it. I was left pretty upset after all this.
