On Diabolos they are a blight. Over 40 names blacklisted in 2 days. Most are still there.
In Ul'dah, you can walk into The Quicksand (the inn), go to where Momodi is and see several level 1 Gladiator spambots all standing in a clump with their heads bobbing as they continuously spam shout.
There has been some removed (I think), but several of the same ones have been there for over a day.
