Bots Players in hero mode X getting ex without playing

Today i found two rooms (Hero mode x ) which had afk BOT players they shot randomly so they wont be kicked by afk SYSTEM... i played 17 rounds so i was able to save the replay . The problem is now i cant send the replay to the support ... how did u report the players if the replay is so high ? it is really unfair because they dont play and they get EXP it isnt the first time i already reported a farmer room in EU...and the players got a punishment there (Rank reset)
