enemy team went afk at once

so, i was playing ranked and suddenly enemy team all went afk, during that time we pushed and some time later only 3 of them came back, they were talking about DDOS or whatever it is, is it actually possible that on of my teammate was doing something ? how do we prevent ourselves from such thing, if it exists
