Significant problems with IntenseDebate Comment Statistics & Importing

First, the good things:
I have recently installed IntenseDebate on my Blogger, http://zamolxis.name. I was pleasantly surprised with the installation process and the commenting system is a MAJOR improvement over the original Blogger commenting system (which is most likely the worst in the industry). I immediately noticed a number of problems. I thought they were all related, but as it turned out, and as the CSR who answered my complaint correctly pointed out, I was not getting emails because of an error in the address. Despite the problems below, IntenseDebate has a pretty good Tech Support, at a time when other corporations outsouce it to drones whose accent is incomprehensible. They also deserve credit for maintaining support on a service offered free of charge, at a time when most likely their priority is integration with Wordpress.com. So despite these problems, I am very happy they exist and they didn't cut support for Blogger.

The problems:
1. Importing comments crashed. - it's a beta service, so I did not expect much
2. Every single widget has an IntenseDebate linkback. This give the service a "spammy" appearance, particularly since some small widgets are next to each other.
3. Comment count was inaccurate to start with - 800
4. Last comments widget reports date of comment inaccurately - for instance, for comments that happened minutes ago they are shown as 1 or 2 weeks ago.
5. Comment count increases nonlinearly - about 24 comments and 7 commenters later, it reads 848 by 14 readers (2X?)
6. Top articles by comments displays the articles even with most comments, but it shows them with 0 or 1 comment.

What worries me the most is that the comment database may be so corrupt, that even exporting comments may not work later on, meaning that they'll be lost forever.
