And these posts were removed, so "post-count increasers" beware!
Which leads to the idea that you won't be able to get SEO benefit from forums this easy. Moderated forums I mean.
If a forum is moderated it would return better SEO benefit because it won't be full of useless posts with links. Which is why you better take your time, contribute, and get your sought "reward".
Why do you think the easy forums would be good for your SEO? There will be hundreds of other spammers with poor grammar from India, and why do you think Google is blind?
Hope this is a good lessons to forum spammers!
