This should be illegal to the point that whoever is responsible for this tweet should be jailed for st least 5 years.
If Amazon paid someone/company to do this, then it definitely is illegal. But likely no jail for anyone, just minor fines chocked up to the “cost of doing business”
Except the king of disinformation bought Twitter. And “we” not only keep using it en masse, but basically elected him as president.
I dunno about the rest of the world, but the US is way past the event horizon, and the chance of ever arresting people like this is less than zero.
