(Meta) Rules updated, spam removed - eviltoast

I have added some rules to the sidebar of this community. There weren’t any rules before. Give me feedback on the new rules if you have any. Should any of them be removed or modified? Should any new rules be added? Let’s discuss it.
I considered adding a rule against memes and one against propaganda, but I have refrained from that for now.

About past posts. I had decided to retroactively apply these new rules to some recent posts. Usually, I don’t think that is fair, but in this case, I think it is necessary so that the last 10 posts of this community are not just leftypol meme spam, and people get a better idea of what kind of content belongs here. Otherwise, I am letting old rule-breaking content stay for posterity.

I look forward to seeing more great pictures and more activity here.
