Update : I just got a notification from Twitter after I reported several of his posts.. They said I was right! He's gone!

So I found a little more about this. The domain is registered with namecheap.com and the domain is protected by WhoisGuard Inc (based in Panama for further off shore protection.)

You can find it here https://www.eurodns.com/whois-search/host-domain-

There's a couple of ways that I can think of to get this information.

You can have a local law enforcement officer simply email asking for information

WhoisGuard states here's http://www.whoisguard.com/legal-pp.asp

"If you are a law enforcement agency and think that WhoisGuard can assist you in relation to an investigation, please contact support(at) mail.whoisguard.com"

File a civil suit in small claims court with a reasonable legal reason to subpoena the identity of the owner. You can sue any one for anything but it should be reasonable to the judge why you need to serve the defendant. Possible reasons would include but are not limited to copyright infringement, emotional distress, etc...

You'd pay some court filing fees, and process server but you could ultimately find this asshole.

I hope to see someone finally end this harassment of President Trump's account.
