It's my fault. I'll try to find a way to get this data and eventually adjust my code to not include non-exit relays or at least recategorize them as a lower severity.
TOR and people who speak for the service often say that it's safe to run a non-exit relay. It isn't. It's tracked and punished. I know from first-hand experience.

Due to a similar IP reputation service, I couldn't pay my taxes from home this year, just because I had run a non-exit Tor relay recently. It's a big problem.
ETA: I'd also strongly recommend not marking an IP address specially in any way just for having a non-exit relay -- from what I've seen, the clients of IP reputation vendors also don't understand the distinction, so they block both kinds if told about both kinds. It's an attractive nuisance.
Something doesn't seem correct to me about this...
