RTV Stars...Repeat offenders

I think in the beginning these stars are just real people and as they get on camera they start to act and not be themselves. Then other producers like their personality and book them for other shows. Now does this make them a professional reality tv star. I think if you have been on two shows you pretty much become professional at the whole reality tv seen. There is many RTV MTV stars that host other shows on MTV. I guess this makes them a little more professional. But what is professional defined as in this question? Wiki say A professional is a member of a vocation founded upon specialised educational training. Do you think all these stars had educational training to do their job...to be on jersey shore..NO....to be on The bachelor..NO.so in conclusion i dont think any are professional!
