Recently i have got level 8 & bunch of other badges.
My schedule was busy but still i managed to contribute.
I was using Google Maps back in 2016 in a strange city, i always used maps to locate something but unfortunately it alway leads me to wrong location so i have decided to contribute & make this platform effective for others.
But my question is why you people are doing this for free?
Congratulations with your achievements! Well done!
I think you gave answer to your question "Why you people are doing this for free?" in your own lines before: “i have decided to contribute & make this platform effective for others”. We are doing it to help other people like other people help us
I just wanted to let you know that I am relabeling your post to Achievements, where Local Guides share their accomplishments in the program. More information on that matter is available here.
Regarding your last query, I suggest that you check the following article that may clarify your doubts: Why be a Local Guide?.
