Did it even occur to you that saying some things in some countries is illegal and your doxxing victim could go to prison for saying something that looks innocuous to you? Do you know where Mark is from and what all his country’s speech laws are?
If Mark is in such a situation (which he was not, and I knew he was not), then the real culprit is whoever implemented such a completely broken and utterly unfixable ‘anonymous’ comment, and himself for being a security researcher and yet believing that retroactively making comments ‘anonymous’ on a publicly-scrape-able website would protect him against nation-state actors when anonymity was neither the goal nor a documented promise of the account deletion feature he was abusing and then crying ‘dox!’ about it not doing what it wasn’t supposed to do and didn’t do.
