Personal text blacklist
There have been arguments for/against censoring other words and phrases globally, but what about giving the power to remove words/phrases client-side so that they can dictate what is hidden to them personally?
There are plenty of players that would rather never see "gg ez" or "kys" for example. Give players the ability to have their own blacklist and then they wont see it as often. Give them the option to either sensor ("gg ez" -> "%%%%%") or remove ("gg ez" -> "") what they choose. Make the system controlled by regular expressions and the more tech savvy can paste their own rules to the public that block out variations of the same phrase.
The problem of getting trigger happy with a global censor is not as much of an issue when you're giving the players the power to dictate their own personal black-list. If they go overboard with their blacklist then it's of their own doing and it only affects them.
