Use same logic for detecting XP farming to detect "farming" points for weekly club challenges
JanosGeo
I know that Geoguessr has some method to detect games played on easy maps and uses this logic to not give XP for those types of games. The same logic should be used to ensure that games played on such maps don't count towards the total for weekly missions such as the one active now for clubs.

XP farming has already been severely neutered. You cant get XP on a map that scores over 20K, unless its an official map, if there any.
