You asked elsewhere why your site is not performing well in the SERPs. If these are the techniques you've been using to promote it, then I think you have your answer.
Building large numbers of low-quality links will no longer help your site, and may very well hinder it. At best, Google will pay little or no heed to links which you can easily place yourself. Forum posting for backlinks has long been useless. Any decent forum will mark external links "nofollow", as SitePoint does, and link-dropping is more likely to get you banned for Spamming than have any beneficial effect.
However, the OP was not asking about link-building techniques. The thread is heading off-topic and the OP has never returned, so I'm closing it.
