I've never done the paid submission services. However I have done the autosubmissions via the software like AddWeb which hasnt hurt me in any way that I know of - (i didnt put in my real - used email address to avoid the spam) and i cant say for sure if it helped me. Maybe a few backward links found but nothing extraordinary. I hand submit to engines for the most part.
