If you're Buying or Selling a Guide(s), your guide has to be checked by a Mod or Admin, if you refuse this, your thread will be locked, and your post will be hidden. If you post a guide that requires certain things, such as Combat or anything, you must state it in your post, but it's optional is it's a spolier to the guide.
If you Buy a guide then Sell or post it as your own, you'll be banned, anyway, we don't want other people's work leaked for no reason, and making them poor. If you dare to do this, you'll be banned for a month. So please don't do this.
