There are four options each option progressively becoming more realistic.
1. Once you create a newschoolers account it checks your IP and backs it with the rest of the members IP and if you have another account with that IP it will be linked into your signature. It is technical but would eliminate 90% of trolls.
2. Don't allow a new member to make a thread until the new member has 25 posts and a week on NS. This would eliminated all the trolls with ADHD, so that is prob 60% of trolls.
3. IP ban trolls for a month if a troll thread is created (Rowen's favorite one).
4. Leave the NS forums from Mid April- late October
