Just noticed this... sorry I didn't grab the link as an example...one of the ads I looked at came up in the ad feed on a thread, clicked on it to look at the details, and then noticed that it's listed by an "inactive user"... doesn't seem to make much sense for these ads to be shown. Really, they should probably be archived until that user is unbanned or otherwise 'not inactive', as there'd be no way to contact them, right?
Not a major gripe or anything, was just curious why ads from these users would still appear anywhere.
