TBH, whether it is John James, Josie, Dave, Mario, Ben, Rachel, Shabby or any other BB housemate (regardless) - while it's all fun during the show and in the few months afterwards and seeing how the housemates progressed - seeing as the mast majority of them go back to leading much the same lives as they had with perhaps a slightly more raised profile - unless the former housemate has really hit fame level in a massive way after the show... or are promoted by means of the media etc, I find the constant desire to follow them, in their personal lives and in anything that isn't being promoted - completely mental and on the verge of an obsessive, disturbed mind.
IMO - anyone who goes as far as to camp outside homes, follow them around (and I don't mean P.A's - as they are promoted with intention), wanting to know what they are doing, where and when, with who (when the 'object of their attention is not divulging this information themselvs for promotional means) - and this goes for those warped fans of A-list celebs too - indicates to me, an very unhealthy mind.
Most BB housemates go back to a relatively normal life, very much akin to the same life they led before - why their fans can't do the same - beats the hell out of me.
