I will flog myself.

This setting affects the REQ filter submitted to those relays, by requiring the authors to be someone you follow.  It currently does not affect the events selected into the feed, so once those events have been downloaded they aren't filtered out based on (seen on, author) information.

I put some work into fixing that (and other similar inconsistencies) a while back by creating FilterSets which was meant to unify relay REQ subscription filters with feed event-gathering filters.  But as I look today clearly I didn't actually get that work over the finish line. 

 That’s a paddlin’

 All you need to git rid of all the spam. 😂 https://i.nostr.build/bTjWbfZBT3C5uk3e.jpg  

 What is that button for? 

 Shows you notifications from people you follow. Takes out some real people you dont. But all in all very powerful. 

 If you mark nostr.fmt.wiz.biz as SpamSafe it will accept everything from that relay, because you are saying that relay is safe from spam.  If you don't mark it, it will only load notes from people you follow.  I can't tell if you marked it or not.

If it is not marked, and you turned on spamsafe, and then this event came in, that is a bug.

And there is more work for me in this area including:  feed filters to also do spamsafe filtering,  and having a WoT rather than just your following list. 

 nostr.0xtr.dev is not marked as SpamSafe, that's why I attached that picture, to display which ones are marked as safe from spam. And then I went to settings and turned on the SpamSafe toggle (I didn't know that had to be turned one, but nonetheless I did).

And then I posted that note and immediately got spam replies from nostr.0xtr.dev.

But now I'm thinking that that was because I had to restart Gossip first for the SpamSafe toggle to start working. 

 Yeah that is possible that it needed a restart.  Not ideal.
