Who gets their info from something called a trollbox.
People who trade crypto.
Trollboxes make it easy for people to participate in the conversation, but the conversation usually isn't worth having.
Trollboxes made it easy for people just to scream "buy buy buy" or "sell sell sell" in various different ways. You rarely get any decent information from them just biased opinions much like you get in the Speculation sub here (which is basically bitcointalk's trollbox).
There are hundreds of creative ways to scream "buy buy buy" in a trollbox. It must get some results, or they wouldn't keep doing it.
Exchanges keep trollboxes because it's fun. For example, being in Poloniex watching charts for an hour alone would be boring as hell without the trollbox. I enjoy chating with random guys and having some guy with some subtle trolling. Sometimes you can find a legit conversation in between all the trolling. Sometimes predictions are correct and sometimes you get scammed (not me since I follow my own agenda I trust none of the predictions). But overall is a good idea, it brings more traffic and fun.
