I think its not just for a month but they run the signature multiple times for year if im not mistaken ,
they even changing from event after event just to try fooling the community and pretending to trying to
resolved those issues on them but the truth is they are just heading to more valuable victims and extending
their operation a little more before completely leave the forum now,
They canot resolve the problems already because they might just say that they are under the new management. They are well aware that they can't fix their reputation anymore but still trying to run a campaign in the forum hoping they can get some new gamblers to play with their site. With the big number of users in the forum, I think not even 50% will try to check the reputation of the casino, if they see some high rank users wearing a signature, they'll just click it and sign up thinking a high rank member is promoting a casino, it should be legit.
They can't fool people saying that they change their management since I doubt that there's a company or individual investor that will spend or waste his money on a casino have a bad reputation on the community. Its like they are catching those heavy issues thrown to what they claim those old owners of this casino.
And that is bad investment to the new management of those casinos.
Maybe before when they don't have negative trust a lot of people just go and directly gamble without reading or do background checking since they think that its fine and everyone is safe together on all of things they currently do.
