I'm thinking of inviting and allowing niche companies to submit unedited product press releases or other news to be published on one of my sites. I'm sure these same cookie-cutter pr's would probably end up on some competitor's websites, as submitted, with no editing.
I agree with that point..Google did not like that niche posting in Press Release Submission..Please avoid that things. As a results your site may be banned by Google Search Engines...
