Update comment on active-servers

At the beginning of this month active-servers started limitting my network speed to 1MB/s because I was running a Tor guard node. This was their comment (auto translated from German):

Hello,

In order to protect our proxy partners, our main network (AS197071) must be free and unobtrusive on the Internet. If you would like to operate or support a proxy network or support another Tor, you can do this with your own network. Among other things, you will need IP subnets and an Autonomous System (AS), via which the traffic is sent using BGP.

As our ASN appears publicly through an exit as well as with Middle and Guard, this can lead to unwanted attention or even blacklisting by tier providers etc. as a result. The operation of such Tor Middle and Guard in the main network will not be prohibited, but throttled - in order to reduce the attractiveness.

Thank you for your understanding.

With kind regards active-servers Team
