I had to laugh at the 7th name.....
onlyI-BIG-RU
Only? Erm....I don't think so Sergei....or whatever your christian name is.
If someone has 7 entries over 4 casinos, then they are multi-accounting (at least three times), and have just given themselves away. Unlike entering once per casino, multi-accounting is NOT allowed. They should have all 7 accounts shut down.
It may be a ruse to wind people up, get the torches lit etc.
Like if I joined the 4 32red casinos, and liked the look of your name and chose my 4 aliases as 'vinylgreenman' vinylbrownman' vinylblackman' and vinylyellowman'.....
Mr. 'ibig-ru' has at least seven entries! WTF?!
