Sorry to hear that matey.
Yahoo's site guidelines state they don't want to include:
# Pages that harm accuracy, diversity or relevance of search results
# Pages dedicated to directing the user to another page
# Pages that have substantially the same content as other pages
# Sites with numerous, unnecessary virtual hostnames
# Pages in great quantity, automatically generated or of little value
# Pages using methods to artificially inflate search engine ranking
# The use of text that is hidden from the user
# Pages that give the search engine different content than what the end-user sees
# Excessively cross-linking sites to inflate a site's apparent popularity
# Pages built primarily for the search engines
# Misuse of competitor names
# Multiple sites offering the same content
# Pages that use excessive pop-ups, interfering with user navigation
# Pages that seem deceptive, fraudulent or provide a poor user experience
