90 percent of everyone under level 50 is a smurf

Jeff himself said that they do not break the rules just by having another account a few hours ago when someone asked if Smurfing was considered Cheating.

It’s unfortunate, but true.
Gotta reel in the dough somehow.

Right here in this thread;

‘Smurfing’ by the way, means someone who is a high level on a new account.
An experienced person making a new account and starting over with the MMR is not against the rules.

Boosting and trolling are. So, if the smurfs are literally just smurfing to help their gold friend reach diamond or something; that’s against the rules.
