ILoveCSharp, did all your first posts have links in? I made my first posts (I wrote an article, then spun it eight times for the eight properties) without any in. I'm wondering if it's best to make a few "normal" posts, using unique content for each one, for the first week or so, then add some without links. I've also been customising the blogs and profiles a bit (different themes etc).
I didn't use proxies either (I figured as I'm not making them en masse, it would be OK).
Better luck with your next ones, mate.
