Honestly, I don't care about this personally; But, after browsing through a few profiles and posts, I've spotting an overly stupid trend..
The Rep System in general. It basically became a popularity contest on the level of Myspace, including the pointless images (I'm referring to sigs, another story!) that people partake in.
For reasons such as ..
Person A posts " Hitler SUXXORED"
Person B posts " No he did'nt He was kewl!"
Person B proceeds to Negative Rep Person A.
That's only a generic example. Time to be frank.
People are simply using the Rep System as a Tool to advance their popularity and to invoke on others the " I don't care if it's true or not, it's what I said" philsophy by lowering the Rep of the person they don't agree with.
This could simply be fixed by making users input/automatically log their name when they wish to give/take away rep. It puts a face behind those helpful, harmful and insultful words.
It also makes it easier to avoid and identify people who enjoy flaming others views and ideas through the use of it.
