[NBLUG/talk] Are all SEO and social networking builders scams?

[Omar Eljumaily]

I guess this is marginally related to Linux since it's all running on 
LInux essentially.  I got a spam email today that said it would 
guarantee 2,000 Twitter followers or your money back.  Are there 
legitimate techniques for building such followings or do they use 
non-legitimate means like shill followers?  I suppose shill followers 
would boost your ego as well as make it appear that you're more 
interesting than you are.

Same for SEO in general.  The main issue for SEO as far as I can tell 
are back-links.  Are there shill back-link sites?  I suppose search 
engines would be wise to them.  Any legitimate SEO techniques?

Thanks,

Omar
