yahoo messenger filtering blogspot urls?

there's something funky going with yahoo messenger 6. any message i send containing a blogspot url doesn't get through. what's up with that yahoo??? you doing some funky filtering??? is this some sort of censorshit??? er, pardon my french, i meant censorship. =D

as an expirement, i sent out four messages to a contact (numbering each message) to see what would happen:

1 test
2 test
3 lolomoblog.blogspot.com
4 test

and here's what she got:

xxxxx: 1 test
xxxxx: 2 test
xxxxx: 4 test

weird, huh?
