I won 278 euro at Vegas Palms. Then they started asking for all kind of documents. So I started to play Europalace and Royal vegas before they paid me Vegas palms.
Vegas Palms was the first casino she claimed the bonus and won. We've since learnt the OP exceeded the 30% max bet rule while meeting wagering. And her winnings were voided. The OP later accepts she breached the max bet rule at Vegas Palms and EuroPalace but did not breach it at Royal Vegas.
This is rather irregular and if there are several players doing exactly the same - same games and same strategy - something looks very suspect.
Subsequently the OP opens an account at EuroPalace, then Royal Vegas and claimed bonuses at each of these. FL accepted both new registrations and deposits. What is suspect, instead of FL notifying the player of the broken max bet t&c rule at Vegas Palms, FL proceed to ask "for all kind of documents". A clear indication of holding doubt to players legitimacy.
Seems the OP opened the Vegas Palms account and had a withdrawal pending, a while before the EP and RV accounts were opened. If that's the case, FL were well aware of the OP breach, but still accepted the new account registrations and deposits, from a player who according to the FL rep, displayed suspect play.
If the player had lost, then what? Oh yeah FL wins. Seems these type of breaches are only a problem when a player wins

The t&c's relating to bonuses are opened ended. They are not clear.
imo it would serve FL better if they fixed their bonus terms and conditions, spelling them out in plain English. What a player can and can not do when meeting bonus wagering. If making x number of bets on Roulette, then grinding it out on slots, is not seen as "fair play" in the eyes of Fortune Lounge, then make that clear too.
How on earth is this possible?
Bonuses is only a marketing move, try something else...
