My understanding is that the only “rule” is that if you visit the page, you have to post something. It doesn’t matter what. So the premise is that people are posting something random on their phone, and referring to the only rule in the post title, as if it’s an obligation. “Per the rules, I am posting…” etc.

I think. I don’t know. I’m in my 30s, so apparently I don’t understand the internet anymore.
