If I was Plum I'd double the amount a person gives every time they complain.
tbh
I hate to say it, but I highly recommend against that on a different reason than the loss. At this point people are responding directly out of being upset, doing so because they felt betrayed by the host, charging them more for doing so is tantamount to laughing at them for actually trusting the host which could very well lead to players leaving.
Fair's fair, people could read it, but not being able to trust the short version of text and having to read a long form answer is a crap way to treat people enjoying the game.
