See, that's the abuse. That's what's wrong with people. The purpose of rep isn't to rep people back as a thanks. It may seem harmless, but that's abuse. Sure, you can rep them back.. but only if they have an equally good post of contribution. Then that's fine.

Rep isn't supposed to be a popularity contest. It's supposed to show who contributed the most to the forum as a whole.

That's where it went all wrong.
