"improving" the swear filter does nothing. The filter itself, is already flawed as is, including spaces for swear words.
I know if you report someone on iZone, it includes the reported players current client chat. This is helpful in depicting if someone is saying something, dunno if iEra has this same system.
Harassment will always take place on anything that is online. It won't just go away. I am glad people are taking this more seriously, but I also think players should keep in mind there is a block button for a reason.
To build off of that, blocking someone should also block their client chat as well, including PM's. Classic had/has the system, so I don't see why iEra cannot.
