Now I'm more confused. Presumably they would not do this if it was a case of bang to rights. But on the other hand, presumably the "marketing agency" is not completely fictitious and did retweet these fake accounts. There's more story here https://twitter.com/DHSCgovuk/status/1252342364644929536

(I confess to being a little irritated at the scolding tone when it comes to "disinformation". They know perfectly well why people don't trust the government on public health matters and it's got nothing to do with our not having read a little list of fake identification tips)
