I like the new addition of 'investigations', however it feels very incomplete because there are a lot of factors we don't know about the suspected cheater. That's why I suggest letting them explain their guess in a round that was reported. For example, a player instasends New Zealand and their opponent reports the round. The suspected cheater receives a notification and they are given a chance (but don't have to) to explain how they guessed the country. They might write something like "I saw a NZ bollard" or "The landscape looks like South island, I am a kiwi myself" Of course, it easy to just lie but I think it would help because every person knows some metas that their opponents don't and that's one of the reasons why they might be suspected in cheating.
