Discussion Of Everything Legal Is Good
Although in some cases nofollow links can still be beneficial, I wouldn't waste time getting comment links, unless it's for direct clicks on active blogs with real people. There are so many better ways to do link building with that time.
Interesting, some example's ways?
Can you expand on the "There are so many better ways to do link building with that time."
Besides the click-throughs and brand awareness (We don't care about that as much in non-mainstream, though), SEs know about nofollow and don't exactly follow the rules. There are many studies showing that nofollow can still help with ranking better in SEs. I'd still avoid comment spam, though.
