The article misses one of the most common misspelling reason: getting thru Bayesian filters. It has more to do with tech and less with psychology.
This is especially relevant to your point because facebook could EASILY be flagging people based on known pasta messages, for review or shadowbanning etc. They presumably don't do this because "not my problem".
1.Actually the experience of someone I know who's turned screwing with scammers into a personal hobby, who frequently shares notes on this with me.
They don’t care. It’s that simple. I’ve (on Facebook/Instagram) reported scams, and they always say it doesn’t violate their community guidelines. But it turns out the computer “reviewed” my report, so I appeal it, and it’s always “sorry, but we don’t have enough people, so we’re ignoring this appeal. Here’s the report ID for the ‘review’ board.” On the rare chance a human does review it, they say “a human reviewed your report, and you’re right.”
They so much don’t care that, now, reporting scam/spam just says, “thanks for letting our system learn” without a way to make an actual report. I’ve given up reporting scam/spam.
For a real kicker, I’ve reported a literal terrorist threat-like post, and it was still “pending” after a week.
I shit you not, there are people on Instagram who are scamming mentally ill people by telling them that they can train them to do psychokinesis and psychic levitation. I've been following them for months since someone I care about fell for it, and they're amassing really large followings while running blatantly obvious scams. Facebook does nothing about it despite multiple reports.
Even when it's blatantly obvious Facebook always tells me that their account doesn't break their community standards...
This isn't true. English is Nigeria's official language (all Education is in English) and people generally speak English well. Secondly, folks from Nigeria actually use the gist of the article as a flag for filtering out scam i.e. once they open an email with bad grammar, they automatically assume it's scam and ignore it.
[a] English, which is being used for communication internationally just about everywhere, is only spoken well in the anglo-saxon areas.
[b] Someone who speaks bad English doesn't realize it just because they're in a poor country.
