I have no dog in this. I've stayed away from RH as I always suspected they are shady. However, blocking people also from selling is even worse imho. If the exchange does it then that's OK because trading halts for everyone. But if RH does it, people can still sell on other platforms. I would be very upset if my trader is blocking me from selling. I do understand that disabling buying caused the stock to tank, but I think it would've happened even if they disabled both. Was that their way to manipulate the stock price? idk but it makes sense.
