So this exit node is censored by Turkey. That means any site blocked in Turkey is blocked on the exit. What about an exit node in China or Syria or Iraq? They censor, should exits there be allowed? I don't think they should. Make them relay only, (and yes that means no Guard or HSDir flags too) situation A could happen. The odds might not be in your favor. Don't risk that!
Personally I think living with a small amount of country-by-country censorship is preferable to an "exitpolicy:exitsite" method, for example you are always going to get different areas/peoples thinking topics/sites things are acceptable while others dont think so. A tor user can simply change circuit and all will be fine.
Also, if relay operators were able to produce a list of sites that they don't allow exits so, it would allow bad operators to game the system and perform correlation attacks.
Even if a particular relay blocks exits to most .com's, it would still provide a valuable guard / middle service.
Cordially, Nathaniel Suchy

The relay won't [likely] be badexited because neither it nor its upstream is shown to be doing anything malicious. Simple censorship isn't enough. And except for such limited censorship, the nodes are otherwise fully useful, and provide a valuable presence inside such regions / networks.
Users, in such censoring regimes, that have sucessfully connected to tor, already have free choice of whatever exits they wish, therefore such censorship is moot for them.
For everyone else, and them, workarounds exist such as,,, https://onion.torproject.org/ http://yz7lpwfhhzcdyc5y.onion/ search engines, sigs, vpns, mirrors, etc
Further, whatever gets added to static exitpolicy's might move out from underneath them or the censor, the censor may quit, or the exit may fail to maintain the exitpolicy's. None of which are true representation of the net, and are effectively censorship as result of operator action even though unintentional / delayed.
Currently many regimes do limited censorship like this, so you'd lose all those exits too for no good reason, see... https://ooni.torproject.org/
https://en.wikipedia.org/wiki/Internet_censorship_and_surveillance_by_countr...
And arbitrarily hamper spirits, tactics, and success of volunteer resistance communities and operators in, and fighting, such regimes around the world.
And if the net goes chaotic, majority of exits will have limited visibility, for which exitpolicy / badexit are hardly manageable solutions either, and would end up footshooting out many partly useful yet needed exits as well.
If this situation bothers users, they can use... SIGNAL NEWNYM, New Identity, or ExcludeExitNodes.
They can also create, maintain and publish lists of whatever such classes of nodes they wish to determine, including various levels of trust, contactability, verification, ouija, etc... such that others can subscribe to them and Exclude at will. They can further publish patches to make tor automatically read such lists, including some modes that might narrowly exclude and route stream requests around just those lists of censored destination:exit pairings.
Ref also... https://metrics.torproject.org/rs.html#search/as:AS197328%20flag:exit https://metrics.torproject.org/rs.html#search/country:tr%20flag:exit
In the subect situations, you'd want to show that it is in fact the exit itself, not its upstream, that is doing the censorship.
Or that if fault can't be determined to the upstream or exit, what would be the plausible malicious benefit for an exit / upstream to block a given destination such that a badexit is warranted...
a) Frustrate and divert off 0.001% of Turk users smart enough to use tor, chancing through tor client random exit selection of your blocking exit, off to one of the workarounds that you're equally unlikely to control and have ranked, through your exit vs one of the others tor has open?
b) Prop up weird or otherwise secretly bad nodes on the net, like the hundreds of other ones out there, for which no badexit or diverse subscription services yet exist to qualify them?
c) ???
Or that some large number of topsites were censored via singular or small numbers of exits / upstreams so as to be exceedingly annoying to the network users as a whole, where no other environment of such / chaotic widespread annoyance is known to exist at the same time. _______________________________________________ tor-relays mailing list tor-relays@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays
