Yes, Frantech should actually be avoided. But in Miami there are few Tor
relays. A SLICE 512 for $2.00/m or $20.00/y is sufficient for a bridge. https://buyvm.net/kvm-dedicated-server-slices/
Because Frantech=PONYNET (especially Luxembourg) it's just as crowded as:
OVH SAS (AS16276)
Online S.a.s. (AS12876)
Hetzner Online GmbH (AS24940)
DigitalOcean, LLC (AS14061)
Berlin (AS60729)
That doesn't mean that you should turn off your Tor exit when it's already
running. I have some running there too.
Frantech is suitable for the first exit experiences because you don't have any
problems with abuse there, if you follow the rules.
