ShadowRam

1 - You can block/ignore entire instances. (spamming ones)

2 - If it gets big enough, you’ll see legit instances band together and federate only among themselves (white-list, invite only to allow federation)

people will gravitate to these groups of instances if they are well moderated and keep that crap out.

Considering how critical a browser is these days.

I’m surprised there isn’t a very popular Open-Source one that everyone is using.
