why am i chat restricted for a game im getting flamed in??

how do i post images!?!??!?! it'll help explain.. essenrially i had 4 people greifing and constnatly harassing me with pings and in chat, but when i say even 1 thing back or i spam ping, i get penalized it seems. ive already lost my main account to people like this, who sit there and pick pick pick until you break and then report you after the game.. i just want justification that i really do just defend myself and sometimes people get under your skin. i have pictures of all 4 teammates this past game just CONSTANTLY spamming me and flaming me. i have the images as jpegs, but i dont know how to upload images directly to the message board for reassurance?? :\
