Why allowing to report cheaters when nothing is done about it?

It is PR.
Just to highlight the issue a streamer has a video up showing a level 292 cheating.  Not just ESP but full on aim bot. 
I player against a cheat who has two games played.  Playing red sec quads: 49 kills then 48 kills won both matches (obviously)
They haven't played since so very likely a second account where they test the cheat.  So 97kd ratio in red sec HS 83% (same ratio as the cheat the streamer uploaded so obviously a setting in the software) yet the "anti cheat" looks at this and goes "yeah that's all good"?!
