What? Seriously? Badges don't harm anyone. With badges, more people edit and active editors are encouraged to edit more than they normally would, they actually encourage editing, and they have not caused spam nor vandalism. Users who spam or vandalise have their edits rollbacked and they are banned or blocked if they do not desist. And as far as I know, there have not been any users on this wiki who have spam-edited just to obtain badges.
Also, personalisation? So you essentially want to get rid of badges because they don't have pretty pictures in them? I can't put to words how ridiculous that is.
This goes without saying, but B.
