MSN mightn'y like an individual, but AOL had a disagreement with a whole city :)
[link|http://www.xent.com/spring96/0552.html|This] is from quite a few years ago, where AOL's 'decency filters' (sounds about as pernicious as 'ethnic cleansing' or something equally awful...) decided that were you from that town, well, you just weren't.
Had also heard a tale of their 'decency' causing the word 'breast' to be disallowed. Which did wonders for participants in AOL's forum for breast cancer support groups...
