I just thought I would share a few sites that I've run across over the last few months. I would definitely recommend these sites to individuals who are interested in exploring the lesser publicized aspects of anarchist activism. I've definitely learned some pretty useful things from some of these sites. There is also some entertainment value that comes from discovering new and mysterious websites. Enjoy them and try not to be too put off by some of the syndicalist nature of the content. There is gold in them thar hills.

This site has a zine that comes out every few months. You'll see they also have archived zines available to read. I find the content to be pretty high quality even if some of it is syndicalist. Consider scrolling down to the bottom of the page and reading through their first issue. Give it a few issues and see if your interest isn't piqued. I bet it will be. Also explore the rest of the site. There is a blog as well. It's not as interesting as the zine but I like to read them just to see what leftist brethren are up to.
https://hackbloc.org/zineIf you've ever felt like learning how to hack into another's website, or at the very least protect yourself from other hackers, this is an excellent site to get started with. If you get started on the missions, just realize that learning how to code better is a lifelong thing. You're not going to blast through all of the missions. It might be a casual thing you do over the course of a couple of years. But you'll learn a lot along the way. You might even gain a greater appreciation for how safe free and open-source software is compared to websites built from scratch.

I'm not sure what service this company offers, but it definitely makes me wonder what sort of things are going on in the world right under our noses to which we are completely oblivious.
