Are you doing FB comment posting as your page?

So I been using this sw called wp fanmachine for a while on one of my pages. It's a hard niche to get likes in. But seems it works to a point as I get around 120+ likes a week from comment spamming as my page. What you guys thing? Is it worth wasting time with it?

Good that you can found the likes which is related to your niche then wasting time of free like 4 like system.
