Has anyone won books via this twitter account?

There is a twitter account run by someone who works for Simon and Schuster who runs regular comps for book bundles sometimes posted on here.

I've entered a few and although I don't usually check for winners on any twitter comps (just hope they tag me properly if I get lucky!), I do occasionally see winner announcements (for other people) in my twitter home feed.

I've noticed this book account has lots of book bloggers as their winners, which is not unexpected as they probably get lots of book bloggers entering so there is a good chance one of them will win at random, so I hadn't really paid any attention to this before. However, I've recently noticed that some of the winners have posted previously about receiving bundles of books from this account anyway (freebies for blogging) and some have had previous twitter conversations (personal, not about books) with the account holder as well as talking about meeting up (both in the future and in the past) with the account holder, so I'm wondering if it is worth entering these comps.......has anyone won with them or seen compers (or any non-book blogger) winning? Or is the winner usually someone the account holder already knows? I'm hoping it's at least a mixture - so that maybe the winners really are chosen at random (comp tweets do say RT&F to get your name in the big hat of chance!) with it being pot luck whether they have a winner they know or a winner they don't.

With no T&Cs posted I guess they're free to choose winners that they know, but today I noticed that the winner hadn't even retweeted the comp post as required (unless twitter is hiding it from me or the winner has very quickly deleted it, so to be fair I can't say that for sure )
