As far as I heard, they were sent Cease and Desist letters.
Though one post claimed they were sent a c&d by a SpaceX employee, another claimed X Corp.
Some alts seem to be alive though, such as 'goyimx.com' (uses teapot)
Haven't seen anyone post the actual terms of the C&D yet, but I'm sure it's claiming misuse of blah blah blah, bypassing limits, reverse engineering APIs, affronting Elon Musk himself, etc.
