How come my facebook likes random business pages?

[Thank You]

Like "Australian Mascara" and other worthless business pages that I have never seen in my life. Is there any way to remove it instead of unliking it all at once? Also, my page seems like by itself..

Mine does that too! It pisses me off because it's always all over my feed. Damn spam. ;D

have you ever used a proxy site? they steal your password and email, and then force you to "like" things without your consent - they then "sell" your account information to people who want lots of "likes" and are willing to pay money for them

obviously someone has your password, or you are surfing the internet with an open facebook cookie, which is a bad idea

I used to have the same probem until i realized some else had access to my account. In this case it was my brother putting like in stupid stuff. Try changing you password or maybe checking you apps. Maybe you gave one of them some kind of permission that allows to like.

To me your account is hacked, report it to facebook and change your password.
