Yes, I think I know what you mean. That's where one fan who openly supports Team A and another fan of Team B simply have a bit of banter.

And that then gets taken to the next step where a fan of Team B impersonates a fan of Team A, for laughs, just for a little while. However, they are using a fake account, so they are investing a bit.

But this (as in the genuine, recent quote and NOT about NE) is going to the next step again, where someone is acting like a deepcover fan of Team A for a long period, simply hoping to sow discontent. And they are successful with it too, until people like Fan1 and Fan2 smell the difference. It takes time for that to happen, of course.

That's a lot of dedication and effort by the perp.
