This was a while ago, but Gandi disabled my account - with no warnings - for running a Tor node on one of my VPSes. I then had to send a copy of my passport to eventually get it reenabled. The frustrating thing was that they were also my domain registrar, so during that time I lost all access to my domains as well.
I transferred my domains away after that and decided it wasn't wise to mix services together due to this risk. So now I have domains with Tucows, DNS with Hurricane Electric and VPS with a provider that only does VPS. And I don't bother running Tor nodes any more.
