Mandatory tagging seems a good minimum first step requirement for anybody posting AI articles. Could probably fit under the interpretation of Rule 3 - Be Respectful. Its probably not very respectful to others to intentionally disguise AI use.

So i'm swinging to this being political advertising. Maybe if it was just the picture of the sticker itself there are other foreseeable reasons to have that as a post. But it is the link to get the free stickers. They are obviously part of the getup promotional campaign.

Maybe this post could be left up, and locked, possibly with a moderator explanation tagged, and referred to and linked in the sidebar. The post could act as a case example where the Rule 5 no ads/spamming line was crossed. Might be a useful indicator in future.
