Unfortunately on Bodog once someone is knocked out they are no longer part of the table. I emailed them about it but don't think it's been fixed. Since they're technically not "at the table" you can't block them if they're just observing the table.
At bodog, you'll have to go to the main lobby. Click the 'preferences' tab, then the 'game details' tab. There, you check 'block observer chat'. Not sure if it blocks it right away, as I've never done it. I'd imagine that if you close the table, then reopen it, it should work.
