I have had a look at the 2+2 thread, and it looks like FL have been running an investigation, and have now acted upon a list of accounts that show up as suspicious.
IF it is only about "whoring", then FL have handled this very badly, as they have used the procedures for dealing with suspected fraud simply for dealing with "bonus whores". This only serves to fuel the view that "winning from a bonus" is itself fraud, which devalues the cries of fraud when casinos really get a good scamming. The proper way to deal with "whoring" is to send a player an e-mail containing a bonus ban, to rattle on about "suspicious activity on the account" is pretty much an accusation of fraud.
While this has happened to players who have cashed out ages ago, and not played since, making a proper
PAB, following the rules, will at least force FL to investigate the handling of this affair, and justify their actions. This will lead to the player community being able to see whether FL are considered to have handled the situation well, or to have made a complete "balls-up" of it.
This "holy grail" operation was recently removed from the accredited list because they failed to deal properly with issues relating to their rogue affiliates resorting to spamming. They are back now because the spam has pretty much stopped.
Mini Vegas dealt badly with a "fraud ring", and went on a mass locking spree, then failed to communicate with anyone about it. This was the second time they did this in one year, and they even cut Casinomeister out of the loop. This earned them a spell in the "not recommended" section, the next best thing to a full "rogueing".
