Suspicious behavior of players

Okay I was playing bot games (wanted to try some builds) my team got 4 peeps (i.e. everyone except me) running ghost and heal on them (OK no prob may be smurfs) but when game started everyone rushed mid and start running into turrets (I mean bruh seriously) I tried to communicate but no reply that's when I felt like something is wrong cuz mid teemo bot was godlike and whole bot Lane is lost I have to run whole game like an Olympic runner trying to handle lanes while mid feeds and make bots go godlike and then finally at 20min mark they finally said something and it was Gj, Push (wierd isn't it) Thankfully I was playing Olaf so managed to carry to the end (even though bots got teemo zyra voli graves renekton ) but what if I was playing sup that would have been a lost bot game (shame everywhere) I want to know whats wrong with those players I've been seeing them a lot lately. only thing they say is Push and Gj Here is the link to that game http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/2196089298/230757548?tab=overview
