Too much comments daily will sandbox your site

I have read a thread about the "sandbox" experiences, and it was very dreadful. If you think you are using a software for automated commenting on blogs and to generate about more than 1,000 comments a day in random sites with your link attached to your anchor text, your site would have a bigger chance to be "sandboxed", which means your page rank and backlinks could be freezed by Google itself. This is not a legal way to do web optimising, as "sandbox" will definitely destroy your potentials of being a successful website or blog owner, or even as an affiliate marketer. We don't use these softwares or to comment around 1,000 per day, because it's not really stable at all. We should stay focus on manual web optimising, so that our website or blog can't be "sandboxed".
