Another issue is that OVH is over relied upon for public nodes. It's the leading ASN with almost 15%.
They're one of the few providers out there that allow exits. That's why 15% of our exits are on OVH.
For what it's worth, my entire OVH account was terminated as a result of hosting an exit on their VPS line, citing "hosting a proxy" as grounds for termination. They're slow to act on abuse (if you reply with *any* response it satisfies their automated system until a human looks at it), but they do not explicitly support Tor when it comes to VPS's.
