title: How to set up a google map, which allows users to add new markers but not to edit or change already existing ones?
body: <p>I know my question isn't very specific and quite general. Sorry about that. I'm new to google maps API and unsure what would be the optimal or typical approach. If you could just steer me in the general direction...</p>
  
  <p>I want to set up a website, with the following functionality:</p>
  
  <ul>
  <li>displaying a map with markers, highlighting POI's of the users</li>
  <li>everyone should be able to add additional markers (ideally with title, description and a photo)</li>
  <li>BUT: the old markers are not to be changed by anyone but me</li>
  <li>Do I have to worry about API requests? For example, if 100 markers are set and 1000 users load the website would that already result in 100.000 requests?</li>
  </ul>
  
  <p>Thanks for any help</p>
