Names can be changed every 30 days, but they do not become available to be changed to until Day 37 or something. This gives the originating account a grace period to reclaim the name if they so choose.
Beyond that, it's simply an issue of the censorbot flagging names that contain inappropriate tokens, reserved terms (probably staff-related or iconic names associated with former members or it could simply be words that cause bugs for no apparent reason) or are too short or don't use the correct symbols.
