A while back I noticed a new guy competing for the same keywords as me. After a bit of investigation, it turns out it's actually my old competitor under another account.
He's basically ensuring he's always either 1 or 2. I know this is against Google's terms, but if I report it are they likely to do anything about it? Or should I stop whinging and just do the same?
The problem really stems from, if your competitors get tricky and make the site with just a small difference in content/layout/links, and then link to their old site all over the place, G won't do a thing about it.
