Hard to comment on unless you tell me where you found it.
There are always a number of new “watchdog” sites who are trying to gain foothold. They have angry people (maybe sore losers) post about places, and then when the place doesn’t reply to the wannabe watch site, they get blacklisted.
Most online gambling places are likely blacklisted one place or another.
I don’t believe most of them, with the exception of Casinomeister who actually knows all the operators and talks to them and I see him doing so at all the conventions.
He is the only one with access like that, and most others may have a couple of programs or operators or software groups they have some influence with, but they get ignored by the rest.
You can’t just pitch a tent and declare yourself a watchdog. You need to have people listen to you first.
