I don’t think so UNTIL the blog owner decides to delete his old blog comments from DISQUS itself.

“If a blogger decides that your comment was not worthy and deletes it can you still retrieve what *you, the user* submitted to Disqus?”

Yes. Your dashboard have a tab for “Removed” or deleted comments.

“What if others had replied to your comment before the deletion?”

No problem at all. The deleted comment will be marked as “Comment Removed” but all replies to that comment will still be shown, in its original threaded form.

- Disclosure: I do not work for DISQUS, I’m just a user, 2-weeks old if I’m not mistaken :p And I still have to integrate it on my Plaxo, just found out about this today ^_^

I believe content creators should retain ownership and control of their submissions. If you sign up for Disqus’ service as a commenter (not as a publisher/blog owner) what rights do you have?

For example, say you post a comment to a blog which has its comment system hosted by Disqus. When that blog shuts down do posts to that blog disappear from your Disqus comment archive? If a blogger decides that your comment was not worthy and deletes it can you still retrieve what *you, the user* submitted to Disqus? What if others had replied to your comment before the deletion?

When you find out the answers to these questions I’d be interested in how this solution fits with the Plaxo mantra from the perspective of a Plaxo user who would like to leverage Disqus to manage their comments submitted to various blogs.
