Maybe we can see the effect now since they are slowly go away in this forum and we don't see their advertisement much since there's a lot of accusation against their casino. And if they going to bankrupt because of that then its good since it will eliminate those shady casino and those legitimate businesses will remain. But I doubt they will shut down their operation just like that but rather let it run and wait for a victim to come.
To some point, we can't say that they are slowly leaving the forum, because that is a under statement, their presence in in the forum is dead right now and there is nothing left for them, you can check their profile to see when last they were active here in the forum, that is to show to the extent at which we have won the fight against the shady casino.
They tried to make several attempts to come under another identity but we quickly identified and trashed them all appropriately at some point in time.
That must show just how important this forum is to Bitcoin gambling services in general, to the extent they had to try to come back using a different identity several times as you said. Though, if I try to remember I have only witnessed one of those attempts, I believe it was the last one.
I am not even sure why they would try to come again like that, under the disguise of a legitimate casino, if people would realize it is them as soon as they start with the selective scamming again.
Well, the forum is definitely a good advertising space for businesses, most especially, gambling casinos since it is said that gambling casinos are banned from running advertisements on social medias like Facebook, Twitter and the likes, I particularly don't know how true this information is, but I assume it to be true since it's been a very very long time I last saw an gambling casino ads on a social platform
The means I believe is available to casinos to advertise their services currently is through Google ads and public discussion forums like this one, and bitcointalk happens to be fully inline with gambling casinos since both are cryptocurrency related.
So, this is probably the reason why we see that on several occasions after 1xbit left this forum, they tried to come back through various other means that will make gamblers think they are a different business, they know that without this forum their advertising space is very limited.
