This is why I ended up paying extra for a static IP from my ISP. While they always provided me with a public IP outside a CGNAT, I guess whole IP blocks were being targeted by these web security providers.

I guess my ISP allocates static IPs from a separate pool, and probably my IP block neighbors are better behaved (probably SMBs and other fellow nerds), aside from platforms learning that my IP is safe.

Captcha difficulties are way down now.
