Hi, thank you for posting some evidence finally so I can chime in and give you some feedback on its veracity.

First let me explain how DNS rules work for a website.  There is a default * rule which forwards all undefined subdomains to the same IP address.
Go ahead and visit: https://abagofloons.minerpool.net/ to discover what you would have if you weren't so quick to jump to conclusions.  Any name works, go ahead, substitute your own value and confirm.
In addition, please be advised that Chris, the minerpool operator has stopped responding long ago, as long as several months now.  Many of the polls there have crashed out or ran out of rewards to give due to not updating nodes.  Anyone who pays attention to this stuff knows what I'm talking about; I just wonder why you don't and I think it might have something to do with your general disposition in this thread.

Now let's address wattpool and how some pool ops setup their Nginx/Apache2 rules.  They create a similar rule to the one I outlined above for DNS to forward all traffic to a default working site with the variable you chose in your request.  Here, I present you with another super secret pool called https://wattpool.net/ui/aretheyforreal/stats.

As I said in my opening, do please keep posting concrete evidence and let's keep this back and forth going. Personal attacks and opinions are fine, free speech and all but people with critical minds want evidence.
