There are also a bunch at http://bgp.community (linked to the source where
possible instead of keeping a stale copy).

I've interacted with numerous providers who require an NDA or 
pinky-swear to get a list of their communities -- is this really just 1: 
security through obscurity, 2: an artifact of the culture of not 
sharing, 3: an attempt to seem cool by making you jump through hoops to 
prove your worthiness, 4: some weird 'mah competitors won't be able to 
figure out my secret sauce without knowing that 17 means Asia, or 5: 
something else?


Not sure the rationale of leeping them secret, but at least one 
aggregated source of dozens of them exists and has been around for a 
long time. https://onestep.net/communities/
