That's right, you'll become my fwend! (🇪🇺 only)
Once you install this addon, a Battle.net friend invite will be automatically sent to my battletag, Ketho#2355. I will then accept your friend invite and we will have a very happy time, permitted I am not getting spammed by friend invites.
Note that this works only in the same region and there's a maximum amount of 100 friends to a WoW account. This addon serves as a proof of concept that (Battle.net) friends can be automatically added and accepted. So in theory you could make a chatroulette addon with this.
