PSA: being overly 'positive' in chat towards players in a way that you know is tilting...
..is a paper thin mask for your toxic intentions, and it will catch up to you. You may think that you're being clever, but if enough people report you for being negative without the IFS kicking in for obvious hate speech there will eventually be a manual review of your chat logs and real humans won't find it difficult to discover your less than positive intentions. Especially since riot has access to at a minimum the same match history data as everyone else does, which include who died when and where, build orders and timings, and even where champions spent their time on the map.
Throwing out a sarcastic 'gj :D' or other similar 'positive' phrase every time someone dies or otherwise makes a mistake, encouraging someone in chat while you follow them around and steal their farm constantly, etc. may keep you safe from automated systems in the short term, but make no mistake: it IS griefing and it WILL catch up to you.
When it does, I fully expect these kind of people to show up here on the player behavior boards and complain that they got 'unjustly banned' while waving around their chatlogs. I welcome it, for the inevitable smyting that will come once someone takes a moment to review their accounts.
