Are Bulk Link Building Services a Scam ?

[ryosuzuki]

Hi guys,

I've been looking at these link building services that offer you like 1000 backlinks for $100 etc. Are these services real, and even if they do give you backlinks do they actually work. I mean building 1000 backlinks for $100 seems to cheap ? Anyone recommend any good link builders or point me out why these packages are a waste of time ?

I can find you services which offer 1000 backlinks for just $10 or even less.
Of course it's almost waste of time.
These links are from (banned) catalogs and you will not get any links juice from them.
