Sadly, bridges.torproject.org is visited by a number of automated
programs, some of which we suspect are used to harvest the list of
bridges in order to block them.

We hope that adding Captchas to bridges.torproject.org will make it
harder to harvest the list of bridges automatically; the upside being
that the bridges you do get will last longer before being blocked.

I am very interested in any feedback you have regarding bridge
lifetime. Have you noticed that the bridges you get no longer work?
How long do bridges work for you, typically? Any feedback you can give
is helpful!
