I had been reviewing low quality posts and came across one, https://stackoverflow.com/a/12388128/892313, which wasn't great but didn't seem too bad, so I selected "Looks Good." Shortly afterward, I got a educational notice saying
This post has severe quality issues.
It is abusive nonsense, noise, spam, blatantly off-topic or otherwise irredeemable - readers will find it offensive or repulsive rather than helpful. You should delete or recommend deletion when reviewing such posts.
Don't worry, we've already handled this post appropriately - but please take a minute to look it over closely, keeping in mind the guidance shown above.
Looking over the listed criteria, I don't think it is nonsense (grammatical), noise (is on-topic, so far as I can tell), spam (maybe, if the answerer is affiliated with the site linked to, but for an open source project there would seem to not be a commercial interest), blatantly off-topic (related to the question), or otherwise irredeemable. I certainly don't think it is repulsive or offensive.
At worst, it is just a link without any sufficient content to make it useful without the link (which may be reason enough to delete it).
Before clicking I understand, I want to make sure I understand. Is the message I got a generic message which covers all possible delete cases (even those not listed), or is there something about that answer that I missed in reviewing that is covered in the message?
