Is tagcloud still valuable for link building?

[kelfy]

I wonder does tagcloud still valuable for link building? I saw many tagcloud website pagerank drop to zero. I've developed my a cloud website for fun when I was in school. Now I put it up on one of my domain name and get spammed with penis enlargement and casino within 2 weeks. Just wanna get some feedback from you guys about my website. Shell I keep my tagcloud website run?
