Rule 2 of the community guidelines does state that all political pictures (defined as a picture of a politician of any country of any planet) are prohibited and will be removed. So they are not wrong, in spite of the down votes. I do wonder if the community were to have a similar poll today on whether these types of images should be banned how it would turn out, assuming the community has grown significantly since the months that have passed since the prior vote. The second choice was very close in the original poll which would have provided an exception of one political picture allowed per current event.

Edit: here’s the link to the community poll for context if it helps anyone else!

It’s the photo of a politician, which is against the rules that make this community pleasant for everyone else. You can find the guidelines of this community in the sidebar

2…Pictures containing a politician from any country or planet are prohibited, this is a community voted on rule.

You could literally just look at the rules but I’ll do you the favor of copy pasting it directly to you
