It's fine to enforce the rules if we know what they are.
I once posted a photograph by a "fine arts" photographer (whatever that may be) taken during a Dakota Access Pipe Line demonstration (a bad word I presume). It's a powerful image. I'll try to go back & see if it has been deleted.
I suppose Picasso's Guernica would be banned here or is it just "current" politics.
BTW my DAPL photo is still there. Maybe the designation DAPL didn't register!!
