how to check history reader file or manipulated backtest

 
hello apparently some  EAs with kernal.dll import   has fake backtest or manipulated backtest result    i was just asking how can we know what was imported   does mt4 provide any detail as to what this readers are importing   
 
  1. There are no details. Allowing DLLs should be treated like a virus, unless you have the source code.
  2. DLL calls are not permitted in the Market.
