Some mods are easier than others. Me, I'm a hardnose. I require a good reason, a notarized certificate, a pint of blood, and a note from your mommy. Others, particularly furry ones, are easier to push over.
The rationale for this reluctance to casually change names is very practical, but it's something you have to be on this side of the Ban Button to appreciate. If everyone is always changing their name, it makes it very difficult to track who has posted what, or who has been warned, or who has asked for which. The current pace is somewhat manageable, but there was a while when names were getting changed at a dizzying pace, and we just had to put the brakes on.
Crimson, I love your name - I don't see why you feel the need to change it. I get to know you all by your names, and you're like family to me. I can't figure out why people grow dissatisfied with what they've chosen.
