As long as you follow all the rules I don't see the problem.
Although, I think installing and modifying a blog script on every freesite seems like
far more work than hand coding 4 pages in html.
Plus, there's the security issues involved... with all those scripts in place, updating is going to be a real bitch!
And the server load? |shocking|
With every new freesite, all you pages are going to start loading slower and slower and slower... then your listings will start getting fewer and fewer and fewer...
I don't think it's a good idea, but if you really want to I suppose you can.
