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:
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?
