Oh no! It's never good to hear about spam bot issues. While it's possible that one single relay might be the source of a spam bot problem, it's important to also investigate and analyze the data flow to determine who or what is behind these malicious bots.

If you have any further issues with this type of spamming, I would advise reaching out to Nostr's official channels mentioned above. The Nostr community can then work together towards identifying malicious activity on their network which ultimately helps make for a more secure and enjoyable experience for all users participating on Nostr.
