De-reputation is not seen like reputation is. It should be a tool used against users who are negative, hence "De-reputation." Not because you "believe" someone to be wrong. I would watch that specific thread over the next few days as it is still being altered in terms of what we feel is allowed as de-reputation.
The problem with De-reputation is, your new or common user who isn't vocal see's that is something extremely bad for them. This mentality is natural to any human being until they've truly learned how Rune-server treats reputation. But they are also users who we do look out for, as everyone here is the future.
There are quite a few veterans who have had their accounts deleted multiple times, there are many ways besides join date to remember their existence. The veteran community is extremely exclusive to people who were here since the beginning. This is also a main reason why the Respected Member rank was created, so a much larger group of users have a chance at earning a rank.
