hi
I have get more than 1000 bridges and I totally inserted into the torrc file. So I can not notice which bridge is no longer work. The bridges can not be blocked totally. Some bridges seem that no longer work, but after sometime (three days or more) they work again.:-)
You might notice some repetition in the list of bridges you get -- BridgeDB tries to hand out the same 3 bridges to each requesting IP (If you are using the https://bridges.torproject.org distributor). Furthermore, there are only about 1000 bridges in the Tor network, and not all of them are assigned to the https distributor:
https://metrics.torproject.org/network.html
This is by design, so as to prevent a single person from obtaining the entire list of bridges. Obviously, someone who has a lot of IP addresses (e.g. owns a botnet) can get more bridges. This is exactly the scenario for which ReCaptcha was deployed.
Does that make sense?
