That could be a sign that social media giants like Facebook and Twitter are maaaybe indeed making things more difficult for dispensers of bulk election disinformation (at least, the truly criminal versions). On the other hand, it might instead be a sign that disinformation is going to keep growing in every venue, forever and ever, because there's simply not much risk in being an online criminal.
Unless you're just astonishingly dumb about it, a la Wohl.
In the past few years, telephone landlines have become overwhelmed with scammers; you may be among those lucky Americans whose answering machines are far more filled with predatory and criminal hoaxes than they are Actual People You Know. Email is similarly a cesspool of fraud and half-organized crime. Social media is ... social media. And it seems that text messages will be the next fertile field for fraudsters looking to defraud people one-on-one.
What I'm saying here is that this is why we can't have nice things. I'm not sure there's any deeper message than that, other than for the love of God do not believe anything anybody sends you unless you know them, and/or are related to them, and/or have administered specific tests to determine that they have not been replaced with a robot, an Uber lobbyist, or a stock-picking algorithm that has donned human skin. Just ... don't.
Do your part to fight election disinformation. Sign up with the Biden-Harris campaign to make phone calls to swing state voters from the comfort of your own home, no matter where you live. All you need is a personal computer, a quiet place in your home where you can make phone calls, and a desire to kick Donald Trump out of office.
