I have seen no evidence of abusive behavior on her side, and if it existed, we'd have seen it.

But here is the thing: I can block you for any reason I want, and it is valid and not bullying. I can block you for breaking my stupid rules on a dragon you bought from me. I can block you for liking or hating the color thistle. I can block you for selling starving dragons. There is no such thing as an invalid block. It is not bullying. It is curating my experience for my comfort. Which is what she did. (I basically only block bigots, which is my choice. She chose something else.)

But nothing remotely justifies using a third party to get around someone's choice to curate their comfort and buy from them in a visible way. If it was an item, there would have been no way to know.

If just contacting someone gets a week ban... Permanent ban for this on Weevil is not unexpected.
