I noticed that once some player is banned (often for spam/flood, but sometimes it is for other reason), his entire chat is removed from the chatbox. While in case of spammers it may be useful (less trash to see), there are cases where is is not so useful (messages from other people compacts and you sometimes need to find again old conversations) or even harmful (if you were talking with the person and later that person got banned for something unrelated to your talk, then removing the chat will ) I suggest there should be some button to prevent that, some checkbox in settings "[ ] Do not delete chat from banned people" - what is written in the chatbox stays in the chatbox, so if someone is banned, then you can select not to remove their chat. There is slight disadvantage that some spam may be left (the spam could perhaps be in somewhat dimmer color, so you can distinguish it easily), but large advantage that in case the banned person actually said something useful (in addition to whatever he said to get a ban), the text remain there.
