I was going through some Low-Quality Posts reviews, when I came across this post. I clicked "Delete", since not only is it wrong, but it does not really even attempt to answer (recommends something that the Op already mentioned). But I got a strange error message, of the orange popup variety, saying something like (paraphrase):
You cannot delete this post.
So I clicked "Looks Good" instead, and it went through successfully.
I've seen this error message only a couple of times (out of hundreds of reviews), and I'm curious. Is this an error message of some kind? Did I make a mistake? Was this a honeypot trap? Or am I simply not as cool as WATTO Studios and, as such, am not permitted to gainsay him?
