Done, i now have a fully working bot that does like that:
1- waits for a message from the reply Guy
2- when found, replies to it and waits for replies
3- if found a reply to my reply, go back to 2
4- else, after 10 secs without reply, go back to 1

It's in golang, i can send you the code as a private message (are private messages here encrypted?) nostr.fmt.wiz.biz 

 That sounds very cool. I won't have time to run it myself, maybe just post it as a gist? Or keep it secret :-) 

 I think i got banned from relay.primal.net. My ip addresses stopped working one by one, with a few minutes between each (like if someone had to look the logs for them and add them to a blacklist, or something).

If they do that with the spammer too, we may finally get rid of him.
