It might help the "victim" if they weren't constantly posting online and leaking their whereabouts. But hey, how else would they be able to solicit donations?
When I grew up, people used to say that you should never post your personal details online. I think we should normalize that attitude again.
It really makes me wonder why they decided to go with a DDoS attack as opposed to counter-doxxing the operator of KiwiFarm, who also seems to be a donation-soliciting public nuisance and "internet celebrity".
