This is a bit of a followup to my earlier post on obfs4 bridges with formulaic nicknames: https://lists.torproject.org/pipermail/tor-project/2016-November/000809.html
Those bridges are still there, but today I noticed a new weirdness: 756 bridges all having the nickname "ki". 756 is 21.8% of the total number, 3464. At the moment, "ki" far outnumbers every other nickname, apart from "Unnamed":
$ wget -O bridges.json https://onionoo.torproject.org/details?type=bridge $ ./nodeinfo < bridges.json | awk '{print $2}' | sort | uniq -c | sort -rn | head 1519 Unnamed 756 ki 16 UbuntuCore133 6 anonymous 5 hacktheplanet 4 ididnteditheconfig 3 default 3 CoolComputers 2 UbuntuCore95 2 masterFluellen
All the "ki" bridges have other things in common: they run no pluggable transports and they have platform "Tor 0.2.8.10 on Linux". Their last_restarted time ranges from 2016-12-05 17:51:45 to 2016-12-13 15:34:06.
Here is a sample of 20 of them.
$ ./nodeinfo < bridges.json | awk '$2 == "ki" {print}' | sort -k 7 | head -n 20
