[tor-relays] improving the badexit flag process

Hi Nusenu. For the past few days we've been having an internal
discussion about how to revamp our process for flagging bad relays.
Its been dysfunctional for years and it's high time we fixed it.

These discussions are where the wiki you mentioned came from...


I was planning to make an announcement after we got our other
overhauls in place but you make some good points so might as well
discuss this now.

Ideally I agree. Trouble is that BadExiting requires manual
intervention by the directory authority operators, so adding then
removing flags would each create churn for them.

Nope. Trouble is the manual intervention, and actually in the past bad
relay reports have often never been acted upon. A particularly bad
instance of this is what's prompting us to finally fix it.

Those are email links. Is there something we can do to make that more
evident? The text previously cited the address but that felt
needlessly bulky...

We plan on making a closed list for bad relay reports. That might be a
good spot for ExitMap's output too.

[ most of the rest of the questions Philipp will best be able to answer ]

Cheers! -Damian
