The fundamental difference with all these Internet-centric companies is they have no useful support channel, nobody that will talk to you, you're just arbitrarily blocked with no recourse, your money is stolen, end of story.

Traditional banks have branches where you can at least go talk to people. For example in the last year I've been helping an elder relative manage their banking and that has led to the account being blocked a handful of times (somewhat sensibly, as I can see how some of it could've been perceived as unusual activity). But they have a branch with actual humans (no AI bots) so I go in and explain and provide paperwork and all is fixed. By now I'm on first-name basis with one of their support agents so I can just call them directly, they know and remember me and all the circumstances of the account and have the authority to fix things.

Although admittedly, in this case it looks like their previous post was just a comment somewhere, not a full Tell HN post like this one. So I wouldn't get too bent out of shape over this case.
