Yeah ddosing and gaming have a long history. Over a decade ago these type of services were very popular on other games like Halo, CSGO, & runescape. I was pretty active in the runescape PVP community and around ~2010 onwards tons of people were using these types of services to ddos other players/rival teams & even the game servers themselves. It was especially bad on runescape because ddosing had a financial motive (killing someone for their gear that is worth real money is earlier when they lose connection). At the time hiding your IP wasn't as easy as it is now (Skype was super popular like you pointed out, but so were things like teamspeak & 3rd party forums).
