^Or Fizzer just checked out a thread named "alts on the rise" to crack down on the public cases listed. He doesn't always wait for a report.
Technically speaking the ToS can be read as prohibiting the use of multiple accounts. Period.
Practically speaking Fizzer has typically not acted on one player controlling one side of a team, or on someone operating more than one account, as long as it is not used in coin games, ladder*, tournaments or gain an advantage in any way in other games.
*excludes 2v2 ladder, if they are on the same team, and only participating with on team.
