@GregAskew Nope, those aren't just tests. The spam posts shown in the question's screenshot are part of the "Support Number spam" that's been ongoing for a couple/few years now on basically all sites in the SE network, with several thousand identified spam posts. Under normal conditions, the combination of SmokeDetector and metasmoke results in them being rapidly identified and quickly nuked with a mix of automatic and manual spam flags, which prevents most users from being impacted by the vast majority of straight-up spam that makes it past SE's SpamRam to be posted on the SE Network.

@Starshipisgoforlaunch It's spammers spamming. Other than trying to block it (which SE would have to do, and which isn't trivial), the best that can be done is to identify it, then red-flag delete the posts (using spam and/or rude/abusive flags) and moderators destroy the users. Doing that does feed back information into SE's existing spam blocker, which is called SpamRam. For this particular spammer or group of spammers, SpamRam isn't that effective, so it gets posted, which is where Charcoal, your moderators, and you come in to get it deleted.

This wave of spam has literally been going on for months (started in February, IIRC). The spam has just been rapidly deleted by Charcoal and your site moderators. Charcoal is a project by other SE users to help keep spam and R/A content off of all SE sites. SmokeDetector detects the spam/R/A posts and reports them into chat and to metasmoke. Metasmoke then, if the post is seen to be highly likely to be spam/R/A, automatically raises spam flags on the post. Metasmoke is currently down for maintenance for about a day, so it's not raising any flags.
