They&#x27;re not unusable, it just becomes a bit more inconvenient to use them. In my experience, you need to solve 2-3 captchas per site per new circuit (i.e. every 10 minutes, IIRC, although TFA mentions this might have changed recently).<p>Exit node IPs end up on a <i>lot</i> of block lists. This is not specific to CloudFlare. It&#x27;s in the nature of a project like Tor that some of its users use it for things like comment spam, which is one of the things CloudFlare tries to block. This might very well be what most of their customers want - a <i>lot</i> of non-CloudFlare sites block exit nodes completely. They&#x27;re also adding a whitelisting feature for those who want to disable those features for Tor users.
