The modern internet is absolute cancer, so here's some old-school alternatives to some of the major aspects of the modern web. If you have any others you'd like to mention and discuss, feel free.
Instead of social media and forums, try using Usenet and BBSes. There exists many a BBS to choose from, and you can even create your own. Usenet newsgroups exist for many, many topics, and if you wanna create one (ideally based on a topic with some decent amount of appeal), you can even present your idea to the folks at alt.config and they *may* create a newsgroup for you.
Instead of blogging on sites like Tumblr, Myspace, and all those sites with period blood smeared all over them, try running a Gopherspace. It's text-only and uncluttered, and there's no JavaShit to bog down the experience.
Instead of GitHub, host all your code on an FTP site. And instead of posting videos to JewTube, you can make the videos downloadable on that same FTP site, along with anything else you wanna offer up.
Finally, instead of insecure messaging applications, use encrypted email.
