I have picked up a few trolls on Twitter. One who thinks he is witty constantly comparing me to Haman. Another who seems to think it is an attack to repeat things I advocate. I have no desire to ban them, but have no interest in seeing their comments. Annoyingly, Tweetdeck does not allow me to delete individual tweets in ways I can figure, or to screen without banning. Anyone have any advice for either Tweetdeck or if I access directly through twitter.com?
