So I just had my first ever failure here in one of those tests set up by the system to check whether you're paying attention while reviewing posts.
For those who are unaware, the system sometimes sets up fake review tasks for you while you're reviewing posts in many ways, for example removing the score of a very high/low quality post, making a non-sense edit suggestion etc. If you okay a bad post or recommend a negative action for a good post, you fail.The post in question is this: How can I uncompress a *.7z file? (a deleted answer, not the question).
It seems to me that the answerer is suggesting a website which apparently offers the service of extracting various archives (including .7z) online and lets you download the files separately.
One issue I found with the answer (like in many other posts, especially by new users) it's sounds like a forum post instead of an answer which can be corrected easily.
Another potential issue could be that the answerer was promoting their website without disclosing their affiliation (and hence a spam), but I couldn't find any apparent reason to believe that was the case.
So I okayed the post in my review queue and then found out it was already deleted as
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.
Is this deletion justified?
