[tor-dev] How about capping single operators to max. 10% exit capacity of the network?

I'm referring to exit probability.

Lets use "family" that is be more clear.

From the top of my head I know about two
but I didn't parse historic data to be able to give a more precise answer.

Yes I'm aware of the discussion on tor-relays@ where Roger said:

but operators have no effective means in controlling their own share, if
for example another big operator disappears.

I see your point.
Also note that there are operators that would actually appreciate such a
limit because they do not want to run more than X% (see tor-relays@).

thanks for your reply,
