Correct Roobet seems to lessen their way of advertising here in Bitcointalk and not planning
to add more anytime in the future as even their Signature campaigns are now running with 10 members from 60 regular members
It's pretty common for most casino after some years of launching themselves here. If you remember the likes of Cloudbet, Bustadice,Bitsler etc, they used to have lots of promotions here back in the day but as time passed their activity reduced in the forum.
Now I am not saying every casino follows the same path but sometimes these things happen.
