Is Being Trolled By Premades in Ranked a REason to be banned?

I am in s5 and for some reson i got 2 premade gold plyers in the game. That being said they never ganked any other lane which mean i never got a gank (even though i know the jg doesnt HAVE to gank) but that being said we lost the lane becuase i got screwed so hard and the mid lane carried the game so heres the chat that got me a 2 week ban. i dont see how that is salty : ok : aa does 138 with passive that makes sense : this is so tilting she isnt even playing well : she is just stacking potions : and sustaining like a bicth : and what : just get zoned and b usless? : NO F MID : OMG : GANK : SHE DOESNT HAVE FLASH LIKE COME ON. : or just camp top : even though he is alreadu doing fine : ok : im gonna afk : no : how about : when i get pushed in : gank plz : sure : or just complaing about how lux has no flash : and i cant get a gank : wow : now you come? : i dont want you know : thanks : i couldnt really care : someone else can have my lane : says the person with the lux : honestly : if i had i team i wouldnt be inting : but those only exist in lcs i think : im not sure : just like a bad idea not to gank mid : works the same way : no : if you have a proble : mute me : idc : AYYYY : adc dc'd team fight and end : game crash : get me out of this : report for what : not being toxic : im saying the truth : not reportable sry : its not reportable : thers nothing on the report card that says "assiting enemy team" : sorry : now : afking : thtas a reportable offence lol : it does : same : not a sora loser : this game could have been wone : its almost like i AM 12 : same : nah : im still young : its fine : honeslty we could have won if i got a gank : i can blame the jg for not gankking : we could have won if mid didnt snowball tbh. but whatever : gg
