Re: It's fake news folks.
It does look too good to be true, however: The Hollywood Reporter and the New York Observer both say they have been in contact with Lucy, a kid who is learning basic web dev skills in a coding bootcamp, apparently. THR and NYO aren't really the sort of publications to make up quotes separately and independently about the same person. I'll be very disappointed in THR if this turns out to be fake.
Crucially, NYO says it has seen the C&D letter. The WHOIS records also suggest TrumpScratch.com predates kittenfeed.com. I've added a link to the NYO story and some more info about the domains.
If there is a PR viral marketing thing behind this, it's not clear who the beneficiary is - it's a long-winded way of touting a porno website, which we spotted and isn't mentioned in the THR and NYO reports.
One odd thing is that NYO is owned by the family trust of Trump's son-in-law Jared Kushner, also an advisor to the president. You'd have thought that may have put off NYO from running anti-Trump news, but OTOH perhaps the title has proper independence (which is a good thing). It did publicly back Donald as the Republican candidate, though.
Very odd, and a bit of pre-Friday fun. It's not exactly Watergate. Take it with a pinch of salt if you wish.
Update: We've seen the DNS records - the domain was registered on March 22, weeks after "Lucy" claimed to have received the C+D demand so it's pretty much Fakey McFake Fakeface. Sorry. Lessons learned.
