I never understood why so many campaigns choose the same campaign manager, instead of hiring someone who's dedicated to just their campaign.
Obviously business owners would prefer the experienced and established manager to promote them. So, I guess there would be no wonder on seeing the highly recognized managers with so many campaigns.
It's basically like someone who only shows up for work half the time, and his boss doesn't notice it for weeks until an other employee tells on him.
One of the probable reason could be:
This might be an all-new-kind of scam attempt which falls beyond managers measurements in terms of scam control and prevention.
The outcome lesson of this scam might be, it is time for managers to run a bot for checking changes in signature codes for all 7 days and 24 hours.
