How can I get Blind to delete my account?

I guess I made one too many low brow jokes and got permabanned. However, all of my non-moderated comments are still up on their forums and I can easily find them via web search. Because those posts are associated to my Real Name and corporate email address I'd like to take them down.

Here's what I've tried:

+ contact support asking for account deletion, response was: "We are not able to delete permanently banned user accounts."

+ GDPR data erasure request, response was: "Blind is a U.S. company not actively marketing in the European Union. Therefore, we are not covered under the GDPR."

Any other ideas?
