Interestingly, I have <3letters>.one but I think because it's an uncommon TLD and a seemingly random 3 letters, I haven't had that issue.
That’s actually the kind of spam I used to receive on a very short domain with a catch-all.
I guess they loop through short domain names and then try to brute-force the local part.
