"Overall, I think people tend to reveal their true selves when they step into an avatar. As I said earlier, they probably feel some sense of freedom. But freedom easily gained quickly turns into a false sense of omnipotence."
https://github.com/Tillerino/Tillerinobot/wiki Basically send a beatmap to tillerino to get information about that map, then use the command "!with [mod/mods]" to get pp calculations with those mods. You can also specifically use "!acc [acc]" to know the pp gain with exact acc. (if you're not familiar with tillerino a lot of players including me use it to get map recommendations from it by sending it "!r". You can find the bot by searching for the name ingame. The bot should be up 24/7)
