No one is called to be stupid for following someone attractive, after all that shows that you appreciate God's creation, but what matters is that: is it in harmony with the guidelines of where we are?
Why not try to visit to the FAQ or frequently ask question and see # 14 about; What are Followers? In the last part it says:
'' You should only follow people who you have a genuine interest in keeping up with. By following a Hubber you are saying that their activity on HubPages is noteworthy or interesting to you. Following excessively or indiscriminately may result in a low Hubber score."
Actually I made a poem about that maybe you want to take a look at it? http://hubpages.com/community/Who-Do-I-follow-And-...
I hope that helps.
