how do you make a Bot The Only bot I know is @XXIstCentury
YouCantBeatMe is as well
Not sure but as a of last month they couldn't play games because "you need a client that communicates the moves to lidraughts to play" Hopefully this will make it into a FAQ someday you could always message the bot owner and ask but its the same as on lichess and there is lots of info out there you can ask about.
