Yes, the MOBAC app is becoming a serious problem for the <a href="http://tile.osm.org" target="_blank">tile.osm.org</a><br>
server. Earlier versions fake a Firefox user-agent. I have had to<br>
reduce max tile QOS limit downward in an attempt to control the<br>
situation. Allowing mass tile scraping is not sustainable.<br>
A lively thread when I restricted the Faked user-agent:<br>

Maybe we could do some excludes for "good" applications (like proxy caches) and rought limits for "bad" applications?<br>
