I answered Ubuntu 15.04 flashes log-in screen then black:
My honest answer.. remove Ubuntu 15.04 - uninstall it - its not up to scratch, I had so many problems with 15.04, nearly lost all my personal data luckily livecds are amazing, I never fixed the many problems I ran into. Wait about 12 months and 15.04 should be amazing!
And my answer was deleted with the comments:

My answer was not a comment, I did not want to upvote other answers and I did not need 'clarification of any issues' nor did I need to ask a question on the subject. My answer was clear and a good answer, I think. It seems my answer was disliked by the moderator because my answer was to unistall Ubuntu 15.04.
Could someone please explain why my answer was deleted as the comments above just do not justify deletion?
