I spend a lot of time going through Overwatch cases. Simply put, unless the case is obvious, you really cannot say anything other than innocent.

Also, games where a team has a "full stack" or a lobby of 5 friends all communicating, a player could easily look like they're wallhacking when actually their team just has great communication. But, this information is not conveyed to the reviewer.

But one thing that Overwatch does have is the ability to convict someone of griefing. I have fallen foul of these once and faced a 6 week ban from the game. Overwatch does work but the person must be very blatant with their cheats/griefing.

Personally, I think the single most effective action Valve took against cheaters was the introduction of "Prime accounts". Players who link their mobile number to their account can choose to only queue into games with other players that have done the same.

This almost creates a "low priority" queue. If you find yourself part of this, it's generally accepted that you may be against hackers and griefers.
