I have two myspace names, one for politics and one to talk about Japan with my fam and friends back in the states. On my Japan name the myspace ads are all about flights in Japan and such. On my anti-neocon page it's all stuff about Israel, meaning that myspace records keywords and trys to advertise to you through that. I think that is illegal. AOL got in trouble for it a few years back.

Note that these are both from the same computer only I write about different things with each name.
For the record on the Japan name the friends you can see are my brother's gf, my best friend, myself (to test the speed of my page) and my cousin in NC. I don't talk to them about politics just Japan.
On my anti-neocons name those are all political types, A Ron Paul page, a radio host I interview with, a bookstore with my book, and a German translator of a video I did... I talk to them about politics and about Israel of course and I post bulletins about the same things. So notice how the advertisements went?
That is not legal.
