Anybody a smurf-a-holic?

I've always been this way on any account/character based game. On WoW, I'd always be leveling 4 characters at once - my play time was split up like 30 min-1 hr on each character. And on League, it's like, I'll play a few ranked, then when I lose, I'll hop to my other account, play a few. I work full-time now that I'm out of school so I can only really play 1-2 games a night and just swap accounts every day. Or one account I'll use to play with my friends because its low gold so they aren't playing against high gold and plats and feel bad if they get wrecked in a solo lane. Is this against the rules? If so I didn't know I just always did this.

Before anyone says anything, it's not unfair to others because my smurfs are all around the same rank. G5 - G1

Is there anyone else who is like this?
