Yeah it was always a trick scammers used. Scam emails (the more obvious ones - not sophisticated phising) always had typos or subtle grammar errors because authors don't want to invest time in people that are able to spot such mistakes. It's the people that do not read thoroughly that are much more likely to fall for a scam.

I would imagine it might be the same with those ads.

This "just-so" story gets repeated constantly in threads about scams, but I've never seen anyone put up any actual proof. The more likely explanation is that scammers are just bad at English since they're predominantly from poor third-world countries.

Spelling and grammar checkers are free; online translators have been better than that for many years now.

It could be sloppiness, but I think scammers just organically copied efforts that worked, and those were the ones with poor presentations because they pre-filter and so target the scammers efforts more efficiently. The scammers need not be aware of why it works.

		I skimmed the pdf; they show a model where having such an early "filter" is beneficial to the scammer, but doesn't provide any actual evidence that it applies in reality beyond restating the just-so story.
