@antonlopez @switchingsocial@mastodon.at @rnickson unfortunately, that is simply not true. They don’t just block Tor because they “produce a lot of traffic”, but because malicious actors often abuse the Tor service. This is a fact.
And given the fact that a single Tor exit node could be serving both a malicious actor and (for example) a journalist reporting on an oppressive regime, if both use Tor browser, Cloudflare is unable to perform fingerprinting, and thus serve challenges to both users.
