Nickknack said: I think it is done in a manner where only people that have played together can leave reviews, and that you require them to leave some type of comment you can avoid the bot issue. This way, it is really only allowing people the DM has allowed into the game to be able to review them (positively or negatively) and same for people who you've recently played with. That method, the easy way to get 5 stars is to make bot accounts and have them be your players.
