They're being downvoted because they're saying the author is incorrect when the author is actually correct.
replyIt's frightening that so many people are convinced the author is correct, when the author never proved they were correct.
replyThe author just collected a bunch of correlations and then decided what the cause was. I've been doing this kind of work for many, many years. Just because it looks like it's caused by one thing, doesn't mean it is.
Correlation is not causation. That's not just a pithy quip, there's a reason why it's important to actually find causation.
Having had three opportunities in my life to diagnose this exact problem and then successfully resolve it by turning off the WAF rule (see my top level comment) - I don't know you or your work history, but trust me, the author is much closer to the truth here than you are.
replyedit: Also, someone commented here "it was an irrelevant cf WAF rule, we disabled it". Assuming honesty, seems to confirm that the author was indeed right.
It's more like I saw a big ball fall down and make a hole in the floor and concluded it must be heavy.
