Re: legally entitled to block accounts
I'm not a lawyer, but I don't think it works like that. An impediment has been put in place against specific individuals from reading statements made by @realDonaldTrump feed. The fact that the impediment is fairly easy to work around probably isn't that relevant to the legal argument.
I'm wary of trying to make an analogy but if someone steals your bike they can't use the argument "but it was a really rubbish lock and really easy to pick" because the principle is that you had asserted your control/ownership of the bike and your intent that it should remain where you left it by using a lock, no matter how bad it was.
