Just checked their Telegram page and apparently they are up on Tor. Will be interesting to see how long they'll be forced out of the clearnet in this instance. According to Null himself at least, this by now is apparently the work of just a single person trying their hardest to make KF disappear.
Though I'll admit, given how much that site is filled with insane misandric TERFs using it as a second Ovarit... I wouldn't cry much over its demise tbh.
