You are allowed to post up to 5 codes on the Friend Codes page. You are not allowed to post more than that, even if they belong to other people. We have no way of knowing that they aren't yours, and it would still be taking more than your fair share of people's attention. If other people that you know want their codes posted, they should do it themselves.

And of course you can post on your blog.
