I am not seeing too many people on this thread confirming that they have been banned or seen others' banned. I think this person just wants other to not join twitter campaigns. There is a difference between direct advertisements and tweeting about things you like personally. I thought twitter's original announcement was foolish and short-sighted. I don't rely on twitter's board of directors to keep me safe from financial ruin. I rely on them to keep their friggin website up and running. Maybe add a new feature or something every now and then.
