Works on my end, you could be detected as a bot or have a bad IP reputation #259

I'm currently working on adding a cf solver that usually works unless you have a bad IP reputation.

Unfortunately there's no way to determine if we're detected as a bot (I'm a user of a static business grade connection).

You may want to also consider including a cf_clearance cookie option per site (including pixiv fanbox) because the CF passing cookie seems to be stored and available as well.

@KJHJason actually, I think there's some changes on the Pixiv side that block things. What I'm seeing on other mechanisms is 403s.

Can't tell but hareku/fanbox-dl#39 (comment) suggests there's problems in the actual auth part and not just because of CF but because non-JP IPs are enforced. I can't debug/sniff what your client does though...
