I always felt so annoyed at the stupidity of the ratio requirements that I do feel some vague satisfaction imaging that it destroyed them (I have no idea what actually happened to cause a shutdown). Everyone buying seedboxes so that they could have fast enough internet to actually earn ratio was ridiculous.
Broadcasthenet still has no ratio requirements at all and is doing fine.
Broadcast the net has a very strict 1 week seeding policy on every download though which makes having a dedicated seedbox almost a requirement. Having been flush with what.cdupload after stocking up years ago on big freeleech files, I kinda preferred the ratio model but can definitely see how it could be restricting for new users.
This was definitely an issue at PTP. You start off with whatever you got invited with as a gift, and if you don't start making up ground quickly, you're basically in a hole, except by freeleech. I realized I had to pay attention to freeleech and participate that way, which worked pretty well, until I built up a suitable buffer, but it takes some doing.
