Not on the current iteration of nostr.watch, no. 

However, I'm rebuilding nostr.watch over the next 3 months and towards the end of the rebuild it will have tor support.  It requires that I have infrastructure to support the NIP-66 daemons operating through a SOCKS proxy. This has a number of complexities when it comes to monitoring a relay, namely, the failure rate and timeout requirements of TOR are significantly higher than with clearnet, complicating backoff and queue retry logic. Due to the higher complexity, it needs to remain as a lower-priority task so it doesn't block more critical developments. I am excited to get it complete, but need to burn through a pretty large list of items first.
