The maidan coup is a straight up fact. Only sounds wild to you because you're so deep in a propaganda bubble that you're hearing it for the first time through a forum comment 11 years late.
Anyone you see self identifying as a tankie is just fucking around because of how meaningless the term is. If you want to insult a Marxist try directly engaging with whatever it is they're saying that annoys you. You might even learn something along the way.
A tankie is anyone to the left of whoever is using the pejorative. Usually because they expressed a critique of imperialism or aren't sufficiently racist towards the Chinese.
Damn that's crazy that the country full of nazis and the fascist military industrial complex masquerading as a country arming them with billions of dollars worth of weapons would be the only two in the world to vote against the glorification of nazism. Totally wild. Oh and they vote against it every time, for years? Wow got to wonder what's up with that.
