It all depends on the area of interest of the casino so betfury according to history has been around for a while now in this forum and their hard signature campaign some time ago but any time their want to run another one they can easily start up again.
All casino interest on promotion is to cover most of the social media and forum. They just have some priorities based on there marketing budget allocations which sometimes makes them focus on one platform that gives them a positive output. Betfury account is still active here but they dont want to engage on user discussion which means they are not interested to socialize on Bitcointalk community.
They are become involved on discussion here when theres a signature campaign or an important issue that involves them.
