As I mentioned, a tech account played by a invividual I don't consider as cheating. As long this tech account is played by a real player which only plays that account.
The problem (and the cheating) is that a lot of players control multiple tech accounts (not played by other players), which makes it just multi-accounts in the form of tech players.
So tech account played by a real player which plays that single account = OK
Multiple tech accounts which are played by the same owner = cheating
That is true.
