Cheating

The problem with this is players dive all the time but nothing gets done consistently.

They need to be punished even if nothing is given. That may send a stronger message that diving won't be tolerated. Currently they only punish them if a penalty is given our something but as you say that is too late for the team who lost out.

Why did this one stand out from other incidents
Is this a new thing I’ve never heard of it before
We certainly won’t miss him at Loftus Road
Whatever happens forest wont get their 2 points back

Cheating cannot be condoned but it's been part of football for years. In most matches you will see strikers diving and defenders holding or putting their arms around an opponent. Referees can't really win because if they dont see the offence then they are slaughtered and if they do see the offence and start booking or sending off players they are accused of spoiling the game and being over zealous.

Im not a great fan of VAR but going forward I would expect it to pick up a Dwight Gayle type incident and the penalty decision would be reversed at the time.
