If you also want to delete the user, you can do

dashboard>users>all users then search for the user you want to delete

hover around there avatar and name and you will a bunch of links which one of them says delete

click that

then the next screen which is added from bbPress which says

[] delete all content

[] attribute all content to: {some username}

tick delete all content then confirm deletion

best I can do, I’m on vacation at the moment:-)
