shouldn't mods maybe add some education, instruction or help directing the OP where the correct place to post questions like this is, instead of just blatantly closing with an unhelpful link to the FAQ?
No. Think of the formula for intervention like this:
( Volume of questions on Stack Overflow / Free time to moderate ) * potential to effect change across a large number of people
If we were to answer every single post we closed, we'd literally never have time to close posts (I can hear some cheering in the background).
In this case, the question is demonstrably off-topic, and there's no site on the Stack Exchange network called "Paypal customer support". If there is a site that this question would be welcome on, I do not have enough expertise in other sites to say, and the off topic message already says what I'd say anyway.
At current writing, this question has already received 21 views, where at present, the question you referenced only had 14 views. That means that I've already reached more people with this answer than I could have by leaving a redundant comment on that question.
