-Improve moderation of major social sites with more penalties for harassment. I feel like the lack of proper moderation has encouraged people to be needlessly mean over petty nonsense and sometimes even ruin lives.
-Add more privacy protections
-Force websites that allow both minors and 18+ content to have NSFW filters in place by default for anyone under 18 (looking at you Twitter)
-Getting rid of intrusive ads
-Have websites show posts in order, unless it's something like Lemmy or Reddit where the other options at least make sense
-Websites should be given legal repercussions in knowingly spreading dangerous conspiracies (such as Facebook doing nothing about posts encouraging violence against a minority group in Myanmar eventually leading to genocide)
