ofcourse...did i argument otherwise?

Ofcourse i know tor does this, which is in theory the proper way but....
How does tor classify "proper destination"?
By doing DNS lookups and comparing the answers right?
That's a real problem for tor-operators in countries where DNS-queries are being intercepted by the authorities in certain countries...
The only way for tor-operators in that kind of environment is to use "custom DNS-servers" or put differently "other DNS servers as the default ones of the ISP".
In my current case Turkey, which redirects DNS-answers to block certain domains.
So yes what i want to do is about same as they do but under my own control of which ones get blocked.
The question that remains is: "How can i keep a tor relay running without being flagged as bad, while still doing custom blocking on the tor-client side?"

Brainstorming on my own:
I assume the only way is using a proxy _before_ the SOCKS connection to the tor-client, and setting up tor to use "custom DNS-servers" (term as explained above).
But which DNS-server IP's to use in "resolve.conf" because the nation's DNS servers are polluted...
