Is Algo really 1 ip = 1 user? I always assumed multiple things could be running on one IP since IPv4 is getting scarce, but bare metal networking is not my expertise. I use Algo for the exact reason you mention ("this lan is sketchy") and have been pleased, but I always assumed even if my traffic was mingling, one (possibly secret) court order would out me since I paid with a CC tied to my real name.
