Usually I'm with you but it let me in this time without any XHRs or frames off-domain (my standard µMatrix settings).
It always loads the 'Just a quick check -- We’re checking your connection to prevent automated abuse' page. Depending on my settings I may or may not load the actual Cloudflare checkbox.
And at that point I just don't want to bother with that site anymore really. Obviously I must be some 11th world country on some random sanctioned list (aka Germany). :-)
