Hello!
We finally sat down and documented the current criteria for and the process of dealing with bad relays. If you are interested in that topic, have a look at our wiki page[1] which is explaining the details. We plan to keep that page updated as our criteria and process are evolving in the future.
Feedback is much appreciated!
