Our founder
I still wonder why he keeps advertising himself this way, as if he were charismatic and irresistible instead of toe-curlingly creepy. That stuck in the throat voice is torture to listen to, and his posh boy demeanor is torture x 10.
Also the “our founder” bit as if he were not talking about himself.

Is she actually actually threatening to sue Good Law?
Everything he says and does is in service of publicity for his fundraising efforts. Let’s face it, he needs suckers to finance his grift, since actually winning cases isn’t exactly his strength.
Threaten to sue? I very much doubt that JKR has done anything of the sort – he’s fishing.
He’s a creep of the first order.
