I think you are referring to "Kozak", who was easily the most strident, obnoxious, and persistent "COVID" fear-mongerer here (though there were numerous others). And yes, he/she/it seems to have vanished, not surprisingly.
Actually, Kozak is still actively posting on FR. He/she/it is a big proponent of our sending billions of dollars to Ukraine. From this, I conclude that he/she/it is either just consistently wrong, or a lib/leftist troll, despite claiming to “love Trump”.
Yup, the govt had many gullible stooges posting propaganda on social media sites.
I don’t know how they can sleep at night?
Kozak Is still commenting but his last COVID propaganda post was in May of 2021.
Any apologies forthcoming Kozak, you clot-shot pushing clown?
Yeah, ‘kozak’ quit posting flubros in May of last year.
Now he’s a pro-uke troll.
Figures, right?
Key point here: They walk among us (look at his profile page).
