Describe the bug
I'm currently organizing some of the feeds I've been following, and I've been receiving 503 errors, similar to this issue, but for the above websites. I'm not sure, but it appears that both of them use CloudFlare CDNs, because when I try to access these pages, it'll do that whole “checking the website security” page. I'll add more as I encounter them.

Adding their feed URLs just puts them in as links in fraidycat, with no posts and posting information.
