It was in response to this:

submit url to google is a thing that must 'not' do. It will cause you sandbox for 2-3 month. Your website will be disappeared on google when you submitted

Which is patently wrong since Google provide the means for you to tell them about your site.

If you optimize your site right you shouldn't need to use that.

In theory if google finds your site with out you pointing to it, it shouldn't really be sandboxed

The Google spider bots will find your site eventually, you'll only be sandboxed if they think you are trying to fool their system.

As an aside I just did a search for one of the main subjects of my site - it came up fourth on Google and that's with no SEO whatsoever. Wikipedia and the official site were two of those ranked higher.
