Onionoo does not sanitize any information from relay or bridge
descriptors.  Onionoo processes publicly available information from
metrics, so whatever is sensitive in there is already available to
whoever wants to use it.  Onionoo only makes it more convenient for
people to use this information.

Metrics does not sanitize relay descriptors, only bridge descriptors.
Whatever people put in their relay configuration and that goes into
relay descriptors will be made public.

Very true.  Thanks, Christian!
