I just came across this post:
It's spam (It's a vague statement related to the question, but it's not an answer, and the link points to a commercial sales page). It was posted and instantly self-deleted. My initial thought was: it's a bit strange but it's deleted, so leave it. A few issues though...
Posts flagged as spam are hidden when deleted. In this case it isn't — so I, as a 10k user, can still see this; as can everyone else with the ability to see deleted posts.
Undeleting a post doesn't bump the question. This means there's nothing I can do about the post now, and the user can silently undelete the answer later without notifying anyone (
apart from the "Recently Undeleted" tab in the 10k tools maybe?nope).
The user has accounts on a bunch of sites with no visible posts but has been around for ~5 months. It wouldn't surprise me if the user has done the same on other sites... Letting it pass as a one off on one site may not seem like much of an issue, but if the user is doing it on a bunch of sites then that's a bigger issue.
OK, so I just found Undeletion, Unbumping and the Potential For Abuse so this is a known issue, which is great, but...
What should I actually do?
