Back in the day I was a big Usenet fan. What's the modern solution to the spam issue? At the time, folk wisdom was that the demise was being caused by spam, and that due to the nature of the protocol it was somehwhat unsolveable.

I also wonder to what extent activity pub is the barrier to offline use? For reddit, the Slide client had offline reading and iirc posting. I have been disappointed it isn't available for Lemmy. My guess has been it simply isn't a priority for the devs. Maybe eventually we will get it.

I think it would be cool if RSS got put into Lemmy clients. Example you could make a unified inbox for all accounts by automatically getting the private RSS for incoming messages for all logged in accounts. I have manually set this up a couple of times but its tedious. Completely lacks smoothness when it comes to clicking a link, replying etc. But a client could add a little finesse to fix that.
