I use mchatsuite to filter badwords from the ingame chat, however the unfiltered content shows on the dynmap web chat
Server: someone say shit
CONSOLE: insomniac245: poop
CONSOLE: ~SimonTheDigger: poop
CONSOLE: 13131123: lol!
Sorry - if the filter is not applied to the chat event, we don't see it. This is likely the case for any filter that may be selective to certain users. But, if it isn't changed in the chat event, we cannot know about it.
