Auto link building Software or scripts are easy to use. If you are not careful You can get slap from search engine Using link building Software . I am not an expert but I shall try to explain you the good effects and bad effects about Auto link Submit Software.
Chances are Too Low
when You submitted your blog or website link to thousands of site maybe more. But you don’t know the quality of site. It may harm your search engine rankings. But if you are lucky then you can get some good quality Backlink.
Search engine can slap

Good or bad?
I don’t support Auto link submitting Idea. But its your choice.
The problem with this links: they are too weak. Just a link from a site’s forum more effective than submitting it to a link directory, where the google bot can find thousands of link, and the second: what if they just disable their link page in robots.txt
i usually use it after i blogwalking here and there to get maybe around 50 links then i just close it. cause too much backing in a day is bad.
