I unfortunately can confirm this; the exact same person you show in https://www.furaffinity.net/view/61307896/ has been impersonating you (for a couple of days; they contacted me as they were impersonating another artist before you).
They frequently change their display name and their ID (ID not as often, as that can only be changed every so often).

I hope you filed a complaint against his account. The main thing is that people remain attentive and do not fall for this fraudulent scheme. They are now very actively using the names of many artists and many accounts in different social networks.

Thank you for sharing the information on your page, it is very important.

I have reported them to Discord in the past, but Discord predictably hasn't done anything about it. Plus, scammers easily can just create a new account and lie about it.
The best way against it right now, is by spreading awareness, so that people are more cautious.
