I'm pretty sure I'm dealing with a harasser and I don't know what to do about it.

Blocked a furry on VRchat after they joked about driving drunk. They sent a bunch of people to ask me to "clear the air" over a misunderstanding. I didn't respond to that.

After that I started getting letters in the mail.

Today, I got a delivery of tequila and whiskey, the brands I used to drink heavily. With a long note saying I needed to talk to them or bad things would happen.
