I do support, but what if there are two or more users with the same name, and the only difference is that a letter or two of one of them is in caps? I don't know if there is such a situation, but what will happen if there is?
That's impossible Wolfwinx, you cannot use a name if it is already being used. That's why I'm not just wolfspirit, someone was using it, I had to add the numbers at the end.
I support this. It doesn't hurt anyone and it seems simple enough.
I don't support the limitation however, it's really up to the user's decision if they want to have an obnoxious-looking username. They're in control of their account, not you.
