I have only done it once (on my ThatDamnLlama account). I will only unfan people if they are being complete assholes.

i haven't been on here too long enough to actually get to that point, and besides, i still wouldn't unfan a person unless they started to annoy me to the point of being....just plain insane. even then, i would feel kind of regretful... im not someone who can do that... ^.^ '

people who are rude and disrespectful towards me,and perverts also,lol

I've done it twice. Once to one retard who was spamming the TDI spot with porn (shudder-worthy) and the other...
was also spamming, but with lame stupid excuses alongside it, like
"OMG my dad tried to stab me with a knife"
or
"OMG I just got hit by a car feel sorry for me zomg"
or even
"I know the producers if you're mean to me I'll tell them to trash you on the air muahahahaw".
(hits head to brick wall) Dammit these people make me sick! >.<

**** ya.

No. Well if they start to be offensive or abusive to me then of course, but I haven't had anything like that yet.

only once, but she unfaned me first for likeing the show winx better than w.i.t.c.h (i love them both though)

Usually, I don't.

only if they get on my nerve but i do not have IM all the time so that will not happen XD

Yup if they get on my nerves.

If they are just looking for fans, than of course I'll unfan them....or I'll not even bother adding them
