I'd say it's very improbable to starve trolls by not giving them attention. So long as the community is receiving new members and the new members aren't acquainted with it all works, there will always be someone there to feed the troll. Think of it as a corollary to the Eternal September. That being said, I think there are people post garbage regardless whether they're given attention or not. Kinda like the people who carve dicks and swastikas at bathroom stalls.
