Well, after taking my normal Saturday off from the forum, it seems within such a short period the overwhelming majority is a short 1 hour ban.
Now implemented.
I also changed the vote time back to one minute, instead of two... thus speeding up the process after using it myself. As the time will be used for those who are in the chat, but away... so the painful person will only be present for a minute, then gone.
I am also sure there is a blocked users list... so you can block a user, which should remove their posts from you seeing them or them contacting you in the chat... haven't used it myself, as staff have different functions to members. Will have to go play in it with my test accounts.
