It's been rather amusing to watch the RMT messages of a certain gil selling website evolve into bizarre messages to share their sales pitch - and website address - over the months as SE blocks the old messages.
It's really not worth the effort of adding the spam bots to your blacklist - they don't last more than a couple of hours. It would be nice if SE were to add in a temporary ignore once you reported a spam bot but eventually you'll learn to mentally filter it out when it appears.
Best thing to do is not pay attention to your chat log if you're only there to enjoy someone's Performance. The Performance isn't in the chat log, after all. If the scrolling is distracting, hide the chat log. If you want to still be able to see tells, FC chat, party chat, etc., create a new chat log window that doesn't display /shout and /say and switch to that for the duration of the Performance.
