cut and pasted from the Amazon Connect help page:
Can I remove a post from my blog?
Once a message is posted it can not be removed. However, you do have the ability to edit your message (please follow the instructions outlined above.)
I spent two hours trying to delete my blog posts from Amazon, only to find out that it can't be done. You can go in and delete the body text, but the post and comments remain. that's seriously fucked up.
now i'm thinking i should just delete my whole profile, but that might be impossible too. don't sign up for amazon connect if you want to have control over your posts.
