That whole 'influencer' thing irritates me. Almost invariably the people who set themselves up to be 'influencers' tend to be shallow, vain and superficial. Though of course, there are countless kids who will buy in to their 'wisdoms'.
This guy sounds like a crazee. Totally rubbish domain in the first place.
The nearest I came to hassle was when I ran britishnationalparty.com as a forum about the party. They demanded 'their' name from me. I declined. Things got a bit hostile. But I had young kids at the time and in the end I just let it expire. No idea who picked it up.
I figure this influencer guy was a crazy one off, and I think the more dangerous names are ones that challenge despotic regimes or call dictators out.
