The chaturbate video streams are unencrypted for open room/group chat, it's not hard to record them, I record chaturbate myself. The private show/ticketed show are encrypted, not only you need to be in the private room or have the ticket, also it's much harder to record private shows etc. For me, I used a PHP program to monitor some models, whenever they went online, I would be able to record their videos. For websites like recurbate, they obviously use cloud computing, the model monitoring software, the video stream capture software and video conversion software all run in the cloud, once a video stream was captured and converted, it will be uploaded to cloud simultaneously, that's why the recordings are uploaded almost instantly with the live show, just a few minutes behind .
During the pandemic lockdown, I had like 10T recordings saved, but as you can imagine, a lot of times models were not doing much, so a big chunk of these recordings are just a waste of hard drive space. After Pornhub controversy, Chaturbate tightened the rules, people need to submit ID and get verified, a lot people can no longer broadcast, and for me these are the most interesting people there since they are not cam models and they cam for fun or thrill not for profit, and they were no longer allowed to broadcast freely, the fun was gone, it's not worth time to record the current models on CB.
