Is Blizzard against smurfing?

An actual question here. Do you think Blizzard is against smurfing, I mean it gets them more money but it also makes many people quit the game and is a problem to many people.

This was asked a while back and Jeff stepped in.

A lot of people seem to equate buying a new account and actively manipulating one’s SR/MMR. The former is obviously entirely valid. The latter is not, and Blizzard takes it very seriously.

Bringing minimum comp level up to 50 or 75 would fix soooo many problems.
Don’t understand why they haven’t done that yet.

No they’re not against it. They answer something like our SR system is perfectly placing people in the ranks they belong very fast. Then again, if a smurf collects tons of reports, he’ll get banned
