It's been annoying as hell, though I'm not convinced that these trolls posts move the market too much. Do they? I'm sure SxC can get a few sells in to him, but I don't think he's swinging the market this much. There are other questionable players.
I don't know how much they move the market. Obviously it doesn't hurt to the extent that large sell walls do, but trolls are certainly opportunistic in that they observe walls and then comment here to their advantage, even if they themselves didn't place the walls.
Yeah that sounds like exactly what they do.
I don't get the sell walls either honestly. It seems like a large opportunity cost putting up a wall like that in the middle of a pump. The motivation is still unclear, just like they want it.
