Is there any reasoning to see this message in the close review queue? When does this happen?

  • $\begingroup$ There is nothing in the timeline to suggest as much chemistry.stackexchange.com/posts/168693/timeline It might be due to other account activity by the user. If it doesn't look like spam I would just ignore the message. $\endgroup$

The message

Our system has identified this post as possible spam; please review carefully

appears because at the time of posting user Malek shared the IP address with an offender account who recently posted spam or made an offensive post. Simply put, it's a request from the spam filter algorithm to pay additional attention when reviewing the given post because of the risk of possible spam recidivism from the jailbird account.

The same IP could be due to the use of shared university network or same VPN provider and happens quite often, hence a need for careful review on a different basis. Mods are not allowed to leak user's IP addresses. The most I can say is that an unregistered user posted nonsensical homework request in a demanding and illiterate manner and their question has been flagged as inappropriate for respectful discourse.

As for Is calcium carbonate a Brønsted–Lowry base, a Lewis base, or both?, I edited the question a bit (which I wouldn't do if there were signs of spam) and it has been answered. It looks like this time we all can breathe a sigh of relief and move on.

    $\begingroup$ I think if there is an actual spam flag on the post (for whatever reason), the message appears, too. $\endgroup$ Commented Nov 1, 2022 at 20:08
