they know, but they can't do anything. You can try to not use zoomhack.
I have high mmr accounts, and not care, playing with all functions.
my brother was also told that he was a cheater
he never used Ensage or some other hack
he changed the zoom through the client.dll file
already 3-4 years and was not banned
also 30 +% of players use zoom hack via dota files
I am sure that the valve will never want to ban 30% of players :)
if someone says that you are a cheater, tell him that you have changed the zoom with the help of the dota files
