Bad apples....
Its because people known as script kiddies get programs that perform deniel of service attacks against boards in one of two ways:
1. Having a script repeatedly post to a forum in rapid succession, flooding the system with postings until the hard drive fills up... crashing the system. The old system and the new protect against this.
2. Having a scripting hit the search several times in rapid succession, effectively bringing the system to its knees. The new system protects against this, the old did not.
