WordPress takes all its freedom placing adsense ads on your blog but you as a user can’t! You can’t place ads, you can’t insert any form of code or any other kind of ad. What is this? “Blogger” let’s you place ads, “weebly” does and many others do. I find this really frustating and crapish and will start a campaign against wordpress’s way of doing. This is nothing else but dictatorship. I reccomend you change these restrictive measurements on your blog leaving each user to place ads and make money in total freedom otherwise you as WORDPRESS should not place ads at all on our blogs. Thank you for your attention
You’re joking right? this is a hosted service, so there is no “rights” as far as I know, so basically WP.com have the right to do anything they want. I suggest you look elsewhere if you can’t stand the ads.
