Please implement any form of anti-cheat and cheater-detection apart from "please don't google" and "please report suspected cheaters". Let me be clear: I know that with web-applications that run client-side, it's Google's fault that at least the following are true: you can't disable internal calls to https://maps.googleapis.com/maps/api/js/GeoPhotoService.GetMetadata or change what they return their API does not have HSTS (and that it could still be bypassed) panorama ID can be easily converted to latitude and longitude using SDK or external tools Moreover, I know that it's also a problem with any web-app game that user can do what they want if they are determined enough (e.g. recompile browser to allow some extra actions which would be undetectable on the server). However, you are not even trying to prevent script-kiddies. I'm talking about the lack of any tamper detection on the frontend which could at least detect very lazy or popular cheating attempts or leaking exact coordinates and country code before the round starts (on countdown phase) from your very own API. The worst part is that a cheater can compete with players several leagues above them by simply knowing country plus latitude/longitude useful for large countries (i.e. by knowing 3 values - no map pointer or auto clicker necessary). Such knowledge is almost impossible to detect, as it's usually not distinguishable from country/region metas. It's even worse on moving games, when it's easy to nullify any suspicions from stuff like CZ vs SK or IT vs SM. Therefore, I think that GeoGuessr needs basic protection from script-kiddies and some automated way to detect players with unusually high luck, especially in higher leagues. There's also an additional problem for players to detect whether they have been cheated - currently you allow multiple accounts and there's no way to distinguish a skilled player on a secondary account from a cheater. Both would look the same - low level (e.g. less than 15), playing in Gold or Master leagues, having a high win ratio (>75%).
