As touched upon above, developing an entire new personality and using 3-4 of them daily over a period of weeks, much less months, is impossible for the average human being. It would take a sociopathic personality to be successful at it.
We can all get away with a sock or two, but use them sparingly such as with a drive-by post. Continually using multiple accounts successfully on a daily basis is impossible for a normal human being. It would take a "special" personality to do so. Intelligence helps, but a warped personality would also be necessary. It's not a normal way to act on a daily or weekly basis.
