If I do this I’m guessing I need to rebroadcast the events that set up my profile or different users, depending on their relay list, will see different versions of it right? Is that possible in Primal or Damus? 

 Nope, they're already on these relays, they pull notes from the network automatically and filter out all the spam 

(That's how I see your note and profile) 

 Great! Thanks.
