I assume you want to know how fast they _could_ detect new exit IP addresses for most cases[0] not how frequently they actually update their exit lists since that can only be answered by the specific site operator. Exit IP address lists [1] are generated by The Tor Project by sending traffic through exits and watching the used source IP address(es). [0] ignoring corner cases that I did not observe in practice yet: like potential exits rotating their exititing IP address at a rate < 1 hour That list gets apparently published once an hour. Maybe Iain or Karsten can add some documentation about how frequent the tests are done for each exit.

The way the question was asked suggests that jiggytwi...@danwin1210.me is referring to another type of blocking that is not the reaction to abuse but the blocking of tor exit IPs - even if there is no malicious activity detected. -- https://twitter.com/nusenu_ https://mastodon.social/@nusenu
