I work in Infosec, and I keep getting the question "why do all these scammers send poorly worded, frequently misspelled, obviously fake emails by the millions?"

And I lay it out for them. The short answer: is because it works.

If they send 5k emails out, asking for $2k, all they need is for a small percentage to fall for it.

They know how much effort to put in to get a specific return.

Why can't that be the same idea here? Pick out the ones who don't ask questions, or take 2 seconds to Google something, etc. Whip them into a frenzy. Then steer them to a specific site. Or to donate. Or even just start following whomever wrote this out, to be convinced to donate somewhere later.

My understanding is the poorly-worded emails are deliberate, to act as a filter to get rid of the folks who are unlikely to fall for the scam. This means the scammer isn't wasting time talking to these folks when they'll never pay up.

This doesn't apply to the diagram. In this case, it wasn't just laziness. The author actually added not just the "5G Freq" label, but added "Bass", "Treble", etc in the exact same style. And I know they added this because I dug up an original diagram where the labels look different. The author erased the original labels and re-did them (and added "5G" to the pre-existing "Freq"). This was clearly a joke. Someone doing this for real would have simply left off the other labels and only kept "5G Freq" (or would have added other suspicious labels).

Looks like "they" know their customers.
