So far as submitting to here there and everywhere, maybe overdoing the same article will lead to a diminishing return on time invested but I don´t beleive for a second it can actually "hurt" your site.
There is a very logical reason why getting links from bad neighbourhoods and having spammy inbound links our Google bombing your own site can´t do your site any harm...
Because if it did, then I could simply employ a company to do this to my competitiors all day and all night long and watch them fall out the rankings.
That isn´t going to happen and it would comepletely ruin the whole concept of ranking if it were allowed to.
Off site SEO cannot do any damage. ONSITE SEO certainly can.. if it is you sending links out to bad neighborhoods, keyword spamming and using other blackhat then you can be penalised for it.
The real problem with SEO is all the bullshit. People spout it all over the internet - "secret linkjuice" "secret ways to rank nr 1" "secret this that and the other" and 95% of it is complete rubbish designed to tempt you to part with your cash for a secret product that nobody else is using.
If anyone came across a secret way of consistently ranking number 1 very quickly for any keywords they wouldn´t need to sell this as a service - they could just built a couple of websites and retire!
The real problems with SEO is misinformation
