Is there anything that I can do about a seller threatening to share my name around because of a refund due to Lost package?

Hi there, if this is against the rules then please let me know.

I want to know if I have any options on Bricklink for responding to a rather nasty seller.

I had an order that was a week late, not update me on the status through USPS. I placed a help request from USPS, and messaged the seller through brick link to let them know what was going on. They responded very aggressively, talking about how they could offer a refund, but that they would stop list me for wasting their time and money. Today (A day later) I responded that yes, I would like a refund. This is because USPS let me know that they looked into my request, and could not find my order. They assume it to be damaged or lost.

In response, the seller stated that he would refund me and would make sure to share my name around here and other places to "warn" sellers about me. I don't really care that much about the opinion from a whiny/childish seller, but is there any way to report this behavior on the site? I figure it's kinda unprofessional to threaten sharing a customer's name for something out of their control.

If not, oh well. I just thought I'd ask since I'm new to the site and this is one of my first interactions on here that has turned sour. Thanks!
