There was a difference with that situation. The information that was being posted was being uploaded onto Steemit's servers (actually AWS since they rent them). That is where all the pictures and videos (along with text) go. The text is sent to the blockchain and those posts can still be read. Any pics and videos associated with it are gone though.
The gambling games we are discussing are not one Steemit. Other than announcement posts, these games have nothing to do with that company. They are operating elsewhere.
As for the online gambling, I am not sure since it isnt something I am not into. I am sure it enters into jurisdiction problems and an assortment of other things. But again, if it is, that is not Steemit's problem since it is not offering that service. In that instance, it would be yours or mine if we partook.
