A while back I bought a domain for a car name using the ".org" TLD.
I got a C&D from the car company, which I promptly ignored because I was young and I thought it was ridiculous that a company should be allowed to regulate the internet.
I was making about $1K+/per month in revenue from Google Ads because I was putting relevant content on the site (I never pretended to be the car company).
About three months in, GoDaddy, my registrar, took my domain name and gave it to the car company without notice.
They also charged me $30 for the administration fees associated with handling that transaction.
I learned a pretty good lesson that day. This is why I adamantly support things like net neutrality. I find it repugnant that companies can do stuff like this.
Net neutrality has absolutely nothing to do with trademark infringement. The lesson you should have learned is not that the Internet should be free, but that you cannot earn money by using someone else's name in a similar context (which in trademark law is their legal property), especially after they find out and ask you to stop using legal methods.
When you say relevant content, do you mean about the car company? That sounds like infringement if so, and you're lucky they were satisfied with just taking the domain.
The reddit discussion appears to be three months old. If you visit the domain now, it appears to be a godaddy parking domain. So, perhaps the resolution was that the poster let it expire, and now basically nobody has it?
A quick cruise around variations on "trumpsucks.com", "trumpsucks.net", "notrump.com", and other such domains shows no clear pattern to me in ownership, each being owned by what appears to be a different person, all clearly not owned by the "THE TRUMP ORGANIZATION" that owns trump.com.
It seems like this may be exactly what it seems; an organization believing that people will be fooled into thinking that "trumpd.com" is sourced from THE TRUMP ORGANIZATION. It seems to me that despite the apparent politically-charged subject matter, that this is just a standard trademark dispute. Which I say without reference to whether that's a good thing or a bad thing. (With the explosion of TLDs it's probably becoming an irrelevant thing; only the very largest organizations are going to be able to keep up with this sort of thing in the full DNS space anymore.)
While you may think their claim is frivolous or unfair at the end of the day he has lots of money and if he really wanted to stop you he will. Money talks in the legal system. So I would do the cheapest, easiest thing possible to show them the domain is nothing to do with Trump and see what they say, it is quite likely they are just trolling every domain that has trump in it.
You also forget that to IP lawyers, this probably seems like a clear cut case and an opportunity to get their name out there. I have little doubt that he will have no trouble looking for lawyers willing to handle this case pro bono.
People can own trademarks on mundane names. Looks like trump owns the trademarks for trump in there online entertainment category (apparently for a gambling game)
So yeah looks like there was a potential trademark issue (although geography might be involved)
What this means is do some research before naming your game or company.
Trademark owners have to enforce Trademark rights not a reason to slam "Donald Trump" and his legal team. Same thing happens (particularly with domain names) by any major corporation. [1]
The key part of my statement is "non-infringers." Yes, you can lose your trademark if you don't go after people who infringe it. But you don't have to go after people who aren't infringing, as is the case here.
The OP said "I just took the old landing page down".
We don't know what was on that landing page do we? There could have been something that was infringing in some way.
For the record I happen to have a domain name that I registered that has the word "Trump" in it and is a .com. And I have never been contacted by Trump's legal team. This doesn't prove my point however I thought I would point it out as perhaps relevant.
But there is no trademark infringement here simply from the use of the domain "trumpd". Maybe if it was a real estate site and the logo was in gold letters.
Trump owns the trademark trump for online entertainment. So I would say there is a trademark infringement going on. There is an issue with geography, but considering the name was held in there us that might not be an issue
