David Goulet:
- removal reason
Proximity of fingerprint indicates a clear attempt at insertion in the hashring for an (some) onion address.
Are you also trying to find the matching onion address(es) that the given relay IDs would become HSDirs due to their position on the ring?
Out of curiosity (which onions were they after?) I generated the descriptor-ids for ~180 onions for the coming 90 days and searched the prefixes (3 and 4 chars) of the removed relays in the output and got some hits and although there is a minor concentration about one topic on these onions I'm not sure it actually means these relays tried to become HSDirs for these onions (could be pure coincidence and the concentration around a topic might be caused by a biased onion input list).

After that 6 months, you can find commit like this that removes a bunch of them:

interesting, thanks.
