Browser Support • Re: Cloudflare Verification Loop issues

Surprisingly, I got past https://alternativeto.net/ 's CF verification easily, but any other I've encountered (only a handful as I've come to avoid CF sites for the most part) still gets stuck. I'm wondering why. Have they implemented a PM pass, since we've had a good rapport with them, or did CF institute some more hardcore ..Firewall thingie.. settings that everyone else is just using as default?

Can everyone else also get past AlternativTo's CF?

Off-topic: "Fun" fact, the reason I visited AlternativeTo is because I've started encountering more and more JPG/JPEG images that just won't open in IrfanView. "Can't read file header", and it's stumped me a long time, but it turns out that it's due to some "progressive scan" thingie? So I was looking for some akin to IrfanView, with a forum, that can handle this new-fangled thing.

Off-topic: I wonder if there are samples for such JPEG files?
