Google Maps Data Provider

[Map smurfs Earth]

Hi

I has found that some data edited by community users in maps.google.com is incorrect,
some people has adding wrong data or point of interest purposely and its affect corporate image

what is the difference between Map Makers and Google Place?

i has observed that map data is different in maps.google.com and map markers, why?
(eg. restaurant A is shown in maps.google.com but not in map markers)

Thank you.
