Pretty much. If the thread is 5 years and older, just start a new thread. One problem with old threads, is that they contain so many serious rule violations (incest, underage content, etc) that it can take hours to clean them up. Just let them die. Start a new thread with new perspectives.
So far, these old threads are bumped without meaningful content. Sometimes the new post answers a question asked by a member long gone from the site. Banned, dead accounts. Enjoy reading the old threads, but start a new one if you have something meaningful to say.
