Message troll

Hey,
I was just wondering, There is a troll out there that works by a message, that is basically a wall of text. Ive seen it in a few videos, like :

Its basically typing from down to up I guess, but on 10 lines and not (I think) 150 letters

I know this is probably the wrong section, maybe even the wrong website since this is for hacking, but I was just wondering if anyone knows and can tell me :P

/tell <NAME> Hi. (CTRL+J) Hi. (CTRL+J) Hi. (CTRL+J) Hi. (CTRL+J) Hi. (CTRL+J) Hi. (CTRL+J) Hi. (CTRL+J) Hi. (CTRL+J) Hi. (CTRL+J) Hi. (CTRL+J)

Outcome:

To <NAME>: Hi.
Hi.
Hi.
Hi.
