Rumors circulate all the time about every sorority and fraternity. It does really suck, but as long as your brotherhood knows the truth and continues to believe in your fraternity, none of that matters. People who are jealous love to try and tear down groups all the time.
I have had nothing but great experiences with Pikes I have met. We didn't have them at SFSU, but I've met brothers from UOP. I clearly remember what one of my sisters used to always say, "I'm gonna marry a PIKE one day because they're so fine!" All the PIKEs I have met have been gentlemen!
