please show me an example where with one post you can participate in several contests at the same time. I have never seen such a thing and it would not have occurred to me to add a ban to the rules. Just logically, it's impossible :)

I see your applications with a link to the same post in two more contests from @axeman and I consider this unacceptable. If dear @axeman considers such use of one post normal, then I wish you good luck in his contests, but in mine it is no longer possible, although I liked the photos you suggested. And here you could succeed under the normal state of affairs.
