Honestly surprised that this site was able to function undisputed, entirely on the public internet for this long despite it's entirely illegal nature.
Plenty of these are spawn out of Discord/Telegram networks to coordinate infrastructure. Via the grey/blackhat versions of Twilio.
It's far too common for the operators to give a shit.
They need to sell to people so the Discord/Telegram and website need to be easy to access.
And Discord/Telegram and websites want it to be easy to make stuff with/on them. The alternative is some vetting process where you submit a form for what the site is for and then someone from an authority logs in and checks manually.
This is not conspiracy, the FBI seriously does shit like this.
