Based in a flat, with the owner doing the CS.
This is beyond fishy!
This reminds me of Pamper casino, which appeared to be based in a London Pizza shop, which they denied. Admittedly they were right, it was a takeaway, Google street view was out of date
They are now based in Costa Rica.
Do the council know that Tom is running a casino from his flat? He should be paying business rates, and have applied for planning permission for a change of use from residential to business.
It would be worth doing some analysis of the IP address of the gaming server, and see if this is also in his flat. If so, this is an outright scam. If the server is at least in a jurisdiction that allows such operations, at best this is a very small operation, or a larger operation providing fraudulent operator details to players to hide where it is really based.
All this points to one thing, AVOID!!!!!!
It may turn out to be another Pamper style rogue from Costa Rica using a false UK address, but what makes this even MORE interesting is that it targets ONLY UK players. As such, it would merit attention from Trading Standards and the Gambling Commission, as a UK only casino should have a proper UK facing license, and they cannot argue that UK players just happen to form part of it's international business, and have joined of their own accord based on their own research. UK authorities are never going to believe that a casino that ONLY takes UK players does not do any marketing to the UK specifically, which would be covered even by the existing "must be licensed in a whitelisted jurisdiction".
As for you and your site, your clear agenda of going after the money and not bothering to look past the bank balance, instead of ensuring your visitors get the pick of the most well run operations, is damaging your business.
The more often you ask about a casino you have been promoting on your site because you "know nothing about them", the worse you make yourself look. It is YOU that should be in a position to answer such questions when asked by others, such as visitors to your site.
