Specifically, this:
1. Rossi Adams founded State Snaps.
2. "The slogan 'Do It For State' sprouted organically, and soon became synonymous with the State Snaps brand — a catch-all when referring to [State Snaps]..."
3. Ethan Deyo "had side hustles as domain brokers: buying up URLs and flipping them for a profit".
4. Deyo buys DoItForState.com specifically to capitalize off State Snaps.
5. Deyo starts using #DoItForState and trademarks the name.
6. Adams gets mad.
So Deyo is a total parasite. IANAL and all that, but Adams had should have been able to show prior use / common law trademark protection. USPTO should have denied Deyo's trademark application—or Adams should have been able to get it revoked—then this should have been a pretty clear-cut ICANN trademark dispute ruled in favor of Adams.
All that's to say that I understand Adams' frustration. Though I haven't seen any evidence that Adams tried to protect his trademark legally.
Then, of course, you get into the threats and the gun violence and the ridiculous, immature, illegal stuff.
