I bet you ever clicked on those "Free Smileys for your IM Messenger!" ads. As me (and maybe) you, can hate when you are
talking to someone in your IM and so the person that you're
talking with is a smiley whore(smiley whore is
that person that has compulsive use of smileys, like when he type "Stuff", the S is on fire, the F is dancing, and that annoying thing) you may hate that jumping or talking or driving or whatever doing SmileyCentral smileys.
Also, as those "Free upgrade" or "Free screensavers" that I am sure that are a pleothora of spy, well that MUST be the same with the smileys stuff.
