I was introduced to it by a "girl" that was a fan of my trolling(2010 before trolling was even used) on another app. She used to go by "S3xy Chikana" or something like that.
There was a company called Playmesh that had a bunch of basic online games like link 4 and tic tac toe and they had them in one app. The app came with a community lounge/chat room(worse pedos than graal) and I used to mess with people there. One day she told me to try classic and I did. Logged in, walked around balamb for about 5 minutes while I got spammed with "honor me please" and deleted the app.
About a week later she offer to show me around, so I re-installed it. She took me with her friends from the guild "Mexican Guild" and we got off on the wrong foot with her guild mates. I ended up pkng them until they quit and classics deadliest pkr was born.
