What is the correct behaviour vs Trash Players?

vs players that : - steal lane on purpose when whole team confirm they aren't on that lane - play as premades and are as obnoxious as possible to the solo player - trolls - intentionnal feeders - etc... Cuz obviously you can't say a word, or you expose yourself towards chat restrict/ban. What do you guys do? Thanks.
