We want to shine more light on how we detect and remove malicious relays on the Tor network, how we've developed and use our strategies and tools, and what we're doing to make it harder for bad operators to run attacks.

In the past several years, we have learned many lessons and as a result, established consistent bad relay criteria, built better monitoring tools, improved our cross-team coordination, and significantly raised the bar for malicious operators trying to enter the network.

We have been able to increase capacity and stability with the support of our community. Thank you to everyone who has made a donation in the last few years. You've made it possible for us improve how we fight back and keep users safe.
