>From the download pattern. Humans have a linear distribution of tile requests with most in zoom 14 and 15. Tile scrapers show an exponential increase with higher zoom levels. So if something claims to be a browser but requests tiles exponentially, it is blocked very quickly. With some authors I have agreements that their applications only request up to zoom 15 because those tiles are pre-rendered. If an agent claims to be that application and exceeds zoom 15 it is banned immediately. sylvain letuffe wrote: > > >> Do you have any idea who is causing the load? > > By far the one with more hits (before I rate limited hits) looks strange : > It's refererer is : > file:///Applications/Install/83F78CDD-FB29-E011-854C-00237DE2DB9E/Install/ > and user agent is : NativeHost > file: referrers hints at a local test installation somewhere. So it might be a single person using/copying your map in a local development copy of a website. Are the requests coming from a single IP for a while or are they mixed. sylvain letuffe wrote: > > > The second one has what looks a fake user-agent : > "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)" > (sequential download and IE 6.0, seriously ;-) ) > > Then comes (or alike): > "Dalvik/1.2.0 (Linux; U; Android 2.2.2; LS670 Build/FRG83G)" > The first looks fake, the second does not ring a bell except that it's likely something on Android.
