@1x1 wr holder! I've already emailed him about a month ago to the email listed on youtube, no reply.
@UncleFrank Is right, this warning means nothing other than the fact that he didn't renew his SSL certificate (which costs about $80). He does still own the domain, and it only says that the site is not secure and you could have your password's stolen is because the site can not run on HTTPS, and has to run on HTTP because there is no SSL certificate. This does theoretically mean that someone could steal your password or credit card information, but only if you use it on the website. Jperm.net doesn't have a password system, and doesn't need any payment. The website is completely safe to use, and I still use it almost daily. The loading times are a lot longer (~10 seconds for cloudflare to verify that I'm not a robot) but it's fine.
