I hope you guys will find some solution to this google keywords "conflict of intrest".
But as far as I remember Zi had his "NoobSpot" as server name since early 2015 (in 2014 I'm not sure if his server had this name already - could be also) - so "NoobSpot" server was already visible in google at least in 2015 and "NoobSpot.com" domain was registered in early 2019 - 4 years later, just few months ago. Or maybe I'm wrong about that date ?
So of course you need to get to the point when you find some agreement on that matter. Remember that it's just a name - unless it's a comercial product made for profits - it can be shared.
So c'mon. It's like one british band was singing exactly 55 years ago: "Money can't buy me love" I'm sure it's easy to solve and everybody will be happy finally.
Peace and Good Luck
