Since then I have seen some good results in Google, even page 1 for some terms, but when I looked at the links they have created most of them are what I would call spam: such as meaningless posts on forums and blogs totally unrelated to my site, with my URL in the profile or signature. Also the spun articles don't make much sense to any native-english speaker.
Is this modern-day SEO and perfectly normal ?!? Or am I setting myself up for problems in the future when Google roles out another update ?
