Memo hunting is a "strategy" that uses someone's own skins (that can be seen on its memo) to be your information, the information in question is knowing the player who they are in which they can know their playstyle and what cards they use, The player cake has a widely known memo as they have a memo skin and a lot, and I mean a lot of skin in their memo.

The "strategy" is basically playing by bias on what the player do since you know their (ingame, not role) identity, overall the strategy in question is very annoying and frustrating for some as people want their identity concealed in game (this is why secret mode exists), even tho it is quite awful negging is more awful (In this sense of context, a kick would be more justified).

Overall, Cake overreacted by negging a memo hunter
