With or without "site:" - banned blogs?

[Kamfor]

A client of our company started to write a few blogs on blogger.com to build incoming links to his website. He usually wrote 2-3 comments in each blog with 10-20 links pointing to the frontpage of his website with different keywords. The blogs were quickly indexed by google (within 1-2 days) but after a while google stopped to reindex them even if some new comments were added to the blogs. Our client did a google search on the url of the blogs and found no results so he told me that google banned or blacklisted his blogs, probably because of the heavy backlinking. I checked it typing site:url to google and this way the blogs are listed on the SERP. Now I wonder what is the difference between searching for "http://mysite.com" and "site:mysite.com" - do the results come from different databases?
Interestingly if I do search on a complete sentence from these blogs, there are no results, even if the sentence is in the google cache. Did google really bannes these blogs? If so, why are they listed if I do a "site:" search? Do backlinks from banned sites or blogs negatively affect the rankings of the client's website?

Searching for "http://mysite.com" is going to show pages that have that text on them (ie: backward link pages).

Searching for "site:mysite.com" is going to show the pages that Google has in it's index.

If there are no incoming links to the new blogs your client setup, then they would disappear from Google. Whether or not you continue to post on the blogs, if Google can't detect any links to them, you're not going to be listed for very long.

There are some incoming links to each blog from other blogs already indexed by Google. The new blogs typically were indexed and cached by Google within 1 day and they are listed when I do a search on the url. But about a week later they disappear from the search result of the url search and not listed even if I do a search on sentences which are cached by Google. These blogs only can be found in Google if I do a site: search on them. This is why I think they are blacklisted - I'm just curious if blacklisted sites are still listed if I do a site: search on them or they are completely removed from Google's SERPs? Is there a way to check a site's blacklist status?

I always host blogs for my clients on separate domain names, mostly using the .net extension for this purpose, and i use wordpress.

i suggest that you ask your clients not to host their blogs on blogger or msn my space.
