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.
