Here's a list of messages that my 10-game chat restriction prevented me from ruining games with.

"lmao" -a lot of these when something stupid happens were not sent because of the restriction. "oof" -something I say by reflex when I do something stupid "now that's a lotta damage! :3" -a few of these as well (to be fair it's a tired meme and probably borderline toxic at this point) "ggwp" -also a few of these "/all Ahri you have to hold your charm longer its the only thing keeping me from jumping on you" - one of these in my last game when i was against an obviously new player and wanted to give them some advice against kat... "omg he went to outer space" -also in my last game when someone got knocked up into the sky "WE CAN INHIB GO GO" -this one was a tilter, the inhib turret was still up so I couldn't ping the inhib itself. tried pinging the turret but nobody listened

And that's about it... haven't been flamed by a single teammate since the game that got me chat restricted, so I haven't had occasion to use my extensive expertise in dealing with online bullies.
