This is why a self-hosted WordPress blog is a good place to store all tour posts, media, etc. It can't get shut down because you can just move it. And WordPress is a sane company.
However, you really got to work to get traction from a blog post on social media. It can be done but does takes work.
The bigger problem, yeah, is most social media is walled silos and the companies are treating users like the enemy. I was really active in/tax, people thanked me for advice I gave. However, I'm done with Reddit. Let it rot.
