[tor-relays] Bad experience with hetzner.de and "Trusted Tor Traceroutes" experiment

[Paul Görgen]

Hi,

Apparently even with the lowered rate from time to time the abuse system 
will complain.

I just received an abuse message from Hetzner even though now running 
with the reduced rate. Just so you know. Next time this happens I will 
try to escalate the problem by not solving it in the framework of the 
automated abuse reports. Instead I will put the info about what I do 
into the trouble ticket of the abuse message and put a strong plea to 
contact me about if and how they can stop flagging it as abuse.

Best regards

Paul
