So I just had my [first ever failure][1] here in one of those tests set up by the system to check whether you're paying attention. <sub> For those who are unaware, the system sometimes set 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 posts, making non-sense edit suggestion etc. If you okay a bad post or recommend a negative action for a good post, you fail. </sub> The post in question is this: https://askubuntu.com/questions/219392/how-can-i-uncompress-a-7z-file/960701#960701 (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 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?
