The issue is that, even with streaming, ppl can still hide plugins from their point of view, including filtering out audio callouts. Unless SQEX implements measures to make ACT and plugins ineffective, the R2WF will simply turn into a race to see who can catch the cheaters first.
They can make it appear as if they're playing the game legitimately, but in reality, their screen is cluttered with addons, and they have hundreds of audio and visual callouts running simultaneously.
In the end, I wasn't paying any attention to the race. I only found out about it when a kill video appeared on my YouTube homepage.

So far, this is the fifth time ppl got caught cheating
UCOB: TTS callouts
DSR: UI mods + TTS callouts
TEA: Waymarks hack
TOP: Zoomhack
FRU: hitbox plugin
