title: increase query limitations at overpass api
body: <p>I have an application with leaflet and overpass.api. I use <a href="https://github.com/GuillaumeAmat/leaflet-overpass-layer" rel="nofollow">this</a> overpass-layer plugin to query to OSM data.
  My problem ist, when i query to0 often to overpass.api i get an Too Many request error after 2 queries.</p>
  
  <p><a href="http://overpass-api.de/api/status" rel="nofollow">overpass-api status</a> shows me that there is a limitation. There is 1 available slot, and after a query it blocks my IP for a time period (30sec-3min). 
  Why is my IP banned already after 1 query?</p>
  
  <p>I wanted to make an application to search with OSM tags and receive data from OSM database. My application works , but it is not possible to query often.</p>
