Their response wasn't really correlated with the ban. They were moving in that direction for months, despite the fact that the problem with their platform wasn't the ecosystem of properly marked porn posted by creators, but the avalanche of untagged porn (some illegal) posted by bots which they were unable or unwilling to do anything about (the illegal stuff is why Apple banned their app). When they started the ban, their filter was awful and basically just pushed all the creators off the site (even those who weren't posting porn). As far as I know the porn bots are still there, because the false positive and false negative rate of their filter is atrocious.
