You imply trolling has to have a specific goal? For all I know, and that's especially true for Dave, trolling just triggers a reaction, any reaction. You could also get nothing if the trolled one is a normal thinking logical person.
But with DSReeee you never know what you get. This time - whoever the culprit was - gave us all some insight in Dave's flirting ritual with money, meanwhile implying he could have scammed money before, a very strange set of changing stories in regards to the email, a very triggered pigman who seems angrier than before on stream, and on top a fan who leaves his sphere of goutfluence. If this isn't a win, tell the class what is.
I don't support any troll attempts, especially the bad ones where nothing of the true piggoat gets revealed, but if someone does and it basically just let him dig his own grave by showing just again his true nature, then have that thumbs up fam. And this right now is one of these stories, another weight on the boat of consequences.
