with every free anonymous service there will be A LOT of abuse, because if you break the rules you lose no money, there are no consequences and you can just re-offend right away. even with paid services there is abuse, but thankfully we've only had one CP complaint and a couple more benign aggressive vuln/port scanning complaints
besides that, the whole site looked shady as fuck and i'm not surprised sick people flocked to it
i'm 100% sure this was because of CP because morally one can handle people using his service for spreading malware or db dumps but when people start uploading shit tons of child abuse material to your service at some point you just say fuck it and give up
I don't get why services like this would even be popular for CP. You'd think the people sharing it would be settled in to using torrents over tor... not looking for services like this where a IP is exposed and a VPN might rat them out.
For something so morally reprehensible and heavily pursued by LE, I can't fathom it would be so popular as to keep spilling into every crevice of the internet it can find.
