Read the text again. It said there would be no reason to use a VPN when posting under your real name. It also states Twitter is blocked and you can only access it using VPN.
Don't you see that these two sentences makes no sense? Because one very obvious reason to use a VPN even when posting under your real name would be that this is the only way to do it.
I am not saying that the account is real or fake, just saying that there is an obvious logical error in this specific part.
Ok, twitter is blocked for normal Russians. Why would she post there? Using her real name which the authorities in Russia could easily trace back to her and level increased punishment than what she is already in for?
The only logical sense that comment could make is to imply that the post is a 4d chess propaganda maneuvering by the very same people who are blocking Twitter in Russia.
It’s not blocked for the authorities who are monitoring twitter.
