Just add them on the ignored users section of the bot. There is no way of automatically syncing the forum and the bot, but do you really need something like this if you're not ignoring a new user every day?
Alright, thanks. I just did.
No, I don't ignore new users everyday. There are set of accounts that post new topic everyday in some boards and most of the topics are low quality all the time so I don't like to waste my time to read it.
