A while ago Steve wrote a userscript to change Mr Man's username.
// ==UserScript==
// @name Mr Man? More like
// @version 0.1
// @description yeah
// @author Steve5451
// @match http://forum.blockland.us/*
// @grant none
// @noframes
// ==/UserScript==
var userUrl = "http://forum.blockland.us/index.php?action=profile;u=35550";
var newName = "Mr stuff";
var links = document.getElementsByTagName("a");
for(i = 0; i < links.length; i++) {
if(links[i].href == userUrl) {
links[i].innerHTML = newName;
}
}
I edited the code a bit to change my own name. It's client sided, but makes me feel a little better. Also cheaper than an alt.

PM Badspot and he'll probably fix it.
A few years ago he changed some guy's name from 'ttttttt' to 'Mr. T_T'
Badspot doesn't do that anymore.
