* TCP timeout - A TCP timeout is another way to block Tor traffic on the protocol- or routing-level, however it involves silently ignoring the traffic instead of rejecting it.
== List of RBL Blocking Services ==
## List of RBL Blocking Services
An RBL is a "realtime blackhole list" which is a DNS query-based list used to tag IP addresses as being malicious or as being an origin of spam. Due to the inability to filter or monitor Tor user behavior across the entire network, many Tor exit relay IPs will be marked as threatening (even indiscriminately) which means many legitimate web surfers will be incidentally included in such blocks. This is a subproject to routinely search for and clear Tor relay nodes from RBL and RBL-like lists.
Format:
* [URL] - Description of service/list, threat detection and consequences for Tor users
* [https://www.abuseat.org/] - Composite Blocking List (CBL) - ''A Division of SPAMHAUS''. '''By policy, TOR nodes cannot be removed from the CBL list.''' - Thus, the exact reason for being listed can no longer be established by the individual Tor .Exit Relay operator. Consequently, trying to effectively handle any 'abuse' issues being unfortunately perpetrated from an individual Tor .Exit Relay has become increasingly difficult or impossible when referencing this resource.

== How to unblock Tor users ==
See: [wiki:org/projects/DontBlockMe#BestPractices Best Practices].
If you run a web site on Cloudflare, and you don't want Tor users to see captchas, then whitelist the "T1" country code in the [https://support.cloudflare.com/hc/en-us/articles/217074967-How-do-I-control-access-to-my-site- Access Rules] of the Cloudflare Firewall app. See [https://support.cloudflare.com/hc/en-us/articles/203306930-Does-CloudFlare-block-Tor- this article] for more information.
The best option is not using Cloudflare at all. There are many alternative self-hosting options. See [wiki:doc/TheGreatCloudwallTheGreatCloudwall] for more information.

### List of formerly listed services
These were formerly listed in the above list, but someone (you) found that they now seem to work "more often than not" and thus moved them here adding the move date (do not remove the original reason for listing). Once listed here, other readers will check them from time to time. If they are still blocking "more often than not", feel free to move them back into the lists above. If they've been on this list for over a year, feel free to remove them as apparently having been a temporary IP block, not a complete class-based (Tor/VPN/Proxy) block. Listings older than 3 months should probably be removed.
