Content provider CloudFlare is no stranger to the spotlight, with being accused of protecting pro-ISIS by Anonymous causing it some issues. Now it would seem that they are instead on the throwing end of a claim, saying that requests they get from the Tor network (a network designed around allowing anonymous browsing on the web) are malicious 94 percent of the time. Tor accuses CloudFlare of mischaracterizing their users and blocking its network, with it going so far as to impact normal traffic.
Tor claims that its users are often getting stuck in CAPTCHA loops or outright failures, stopping them from accessing content in even the simplest of ways. In external research, Tor states that CloudFlare was found to block at least 80 percent of IP addresses from its service, with the number increasing over time. The CAPTCHA loop is caused by a measure CloudFlare has introduced that requires users of the Tor network to fill out CAPTCHA’s, but only users of the Tor network will see these.
Tor isn’t happy about this accusation and wants to see evidence regarding their 94 percent figure. Many are wondering how they reached this figure, or even how they deem if a connection is trustworthy. With so many people now using networks and systems like Tor, blocking or making the experience worse for users can’t be seen as a positive step when it comes to providing content.
