I'm gonna post my experience with her. While I didn't have a terrible encounter with her, it still wasn't pleasant, especially with what I know about her now.
Pim's first messages:


And comments on my page:

I'm not on all the time, so I didn't message her right away.
My response:

I told her to try ShadowPlay because they are the most active forum I know.
Pim's response:

The next day I got into contact with one of the request mods on ShadowPlay. She did some investigating and found out I was not the only one she has been harassing. When I found that out, I blocked her. I believe that is the best course of action right now.
And then I found this on her account a couple days ago. She is so upset with people blocking her and not helping her that she had to post links to a lot of accounts, including my own, telling us to "go to hell."
Link to the post never happy and screencap of post with the accounts she called out:

EDIT 2/2/2019: Well, she deleted that post. I still have the screencap though.

I'm not upset about the encounter, I'm just upset she won't try to better herself. Pim is very capable of making these things herself. I know what it was like to not get any notifications on my work that I tried so hard on when I first started. But getting better does not happen over night. You can't expect to get a bunch of followers the instant you join deviantart. And I'll admit, I was discouraged at first, but I kept trying, and five years later I'm at the level I wanted to be because I practiced and I interacted with people.
If you're kind, you'll meet friends on this site and on graphics forums.

Please beware and try not to engage. If you get a message from xxmooniexoclove, block her. That is the best thing you can do. Do NOT stoop to her level and say bad things back. Just ignore it.
