In addition to the apostrophe thing, there’s a couple of other indicators:
First, the quotes are more like greater/less than symbols: «»
Second, does the English seem clunky but in a way that’s hard to tell what’s wrong? Russians do not have any equivalents to the words ‘a’, ‘an’, or ‘the’. If you learned about them in school, at least if you’re a native English speaker, they are called ‘articles’. If you are a linguist or learned about them elsewhere, they’re call determiners. Russians have the words ‘this’, ‘that’, ‘these’, ‘those’ but they only use them in specific instances and not all the time way those who are used to them always being there do. For instance, Spanish or German or Italian or French speakers have no trouble with this. But Russians do. So the words are either missing or completely misused. For example, in the link you posted, they talk about a Blacktivist post that says:
Black people should wake up as soon as possible. Black families are divided and destroyed by mass incarceration and death of black men.
And it doesn’t sound quite right, does it? Although there’s nothing technically wrong with it, most English speakers would write or say “Black families are divided and destroyed by mass incarceration and the death of black men.”
And sometimes the articles aren’t missing per se, but the wrong one is used in a common phrase. For example, most English speakers say: “You have a point”, or “she/he has a point” when we’re trying to say there’s something right about what the other person is saying. However, once I saw a Russian bot account for Bernie Sanders say “Bernie has the point,” as opposed to saying “Bernie has a point.”
So there are a few ways we can try to protect ourselves from fake info.
