I have two, but both in my name. One I used while I was having temporary problems with the other one. I don't see a need for more than one account, I don't do Facebook marketing or anything so don't need it for that.
My secret - Don't make fake female accounts anymore, it simply doesn't work anymore. Make an account with a really attractive guy's pictures. Belive me, the results will be impressive.
I only have one, I thought that they frown on people having more than one account with them. I was told not to do it. Because I was gonna make one for business purposes but changed my mind.
