Why are they saying that link exchanges are in a way "manipulative" to search engines when we are being encouraged to submit to directories? When submitting to Yahoo directory and other directories is acceptable, but link exchanges are not, its telling me that they want to see more 1 way links.

It's telling me that they recognise that those directories are manually built and are therefore, rightly or wrongly, deemed trustworthy.
