How come streamers are allowed to make smurfs

@Xubunnytwo Here's a couple reasons. 1) People level up new accounts enough so that they high enough level to play ranked, then sell the accounts. Cheaters buy these. 2) People make fresh accounts in order to try to farm Wake and/or Wrath badges in beginner lobbies, then either switch to that account themselves or sell it for $$$. 3) They are tired of playing in their high ELO matchmaking and playing in fresh accounts to get easy lobbies, so that they can roll through the lobby like your randoms did. The first two of these cases unfortunately have big markets out there. There are more reasons, but these are among the most common.
