@Plazorn, If you change your GBAtemp theme to throwback instead of the default ones and go to his profile, you'll see a red 'X'. Temp-ban is different to a regular ban being it's a suspension for 7-days or so.
@Skelletonike, I see what you mean. If I change the temp style to red or any other default theme, your username is completely white. My username is also more visible to the eye, so that could be down to which CSS layout is used.
