I didn't know it has been requested. Thanks for telling me.

My main concern is, when a player changes the setting of the applied log filter, the chat log will reflect the new filter effect immediately.
So why not include "black-list" in the log filter so the TELL from a blacklisted person (rmt) could be filtered from current log immediately.

Since I think players have to black-list RMT-tell by themselves for a long while, therefore this enhancement should be helpful,
as many players not only want to deny new tell but also want to remove received tell from current screen ^^;
