Sounds like a surefire way to be banned to me…
There is no longer a need to submit your site to the SE’s. All you need is a link from a site indexed on that particular SE and you will be indexed.
If you are looking to let the SE’s know about your site, here are better ideas:
Submit a sitemap:
Google: http://www.google.com/webmasters/sitemaps/
Yahoo: siteexplorer.search.yahoo.com/submit
MSN: As far as I know there is not a way yet, but you can submit to MSN at: http://search.msn.com/docs/submit.aspx
Hope that helps you out.
BTW – it’s free, don’t pay for auto-submitters
