Repair nodes, Hetzner and their definition of «unlimited traffic»

I recall that Storj Inc. operates (or operated?) their repair nodes on Hetzner, supposedly because of low traffic fees. I’ve stumbled upon this thread, where the definition of unlimited traffic was challenged by Hetzner. I wonder whether Storj Inc. had any troubles because of this “fair use” policy?

as far as I know, Storj use Hetzner. as far as i know hetzner has trafic about 20 TB included in price. As i know small servers has this limits.

Their cheapest auction servers (currently at around 27 EUR/month) come with unlimited traffic. I assume this would make sense for repair nodes.
