A block feature is long overdue, and there's no downside - there's no user that "needs" to see our content for any reason.
The other thing they need to do is allow us to keep things comfortable for ourselves (and optionally for others) by giving us the ability to delete comments on our own submissions. Again, it's long overdue, and there's no real downside. While people could theoretically use the 'delete comments' function to promote their own fake narrative and disallow contradictions, who cares? It's not like memes are consulted as reliable sources of information.
It's amazing though that they're introducing a small, common-sense feature like this, while ignoring the massive problems with the site structure (ie, trying to claim they're banning reposts and politics from a main site stream). Until they get their shit together and put the 'Fun' stream back how it was, no other change makes any significant difference.
