Yeah, IF it's a fear of installing a script that keeps webmasters who might be serious about using blogs as a marketing tool (agree with everything b3achbum and others have said), then DON'T BE! Again, Wordpress for one is nearly retard-proof to install, and it honestly does only take 2 minutes to do, even for the script installing newbies.
Hosting it yourself (along with frequent posts) sends the message to other webmasters (potential trades) that you're serious, and won't have to worry about the freehost's rules and deletion. I mean, even if you DO find a blog hosting service that allows explicit posts, what's to say in 6 months they don't pull a PayPal and change their minds... *AXE CHOP*! .02
