Hi,

I've read that 4 month old thread :
http://lists.openstreetmap.org/pipermail/dev/2011-April/022402.html

And looks like I'm having the same issue (a server drawning under tiles 
scrapers requests)

From reading the thread looks like the user-agent blocking will lead to 
nowhere, distributing client token/password defeates the easy to use concept 
of a public tile server.

So am I left with rate limits ?

I've try to day limit tiles download per IP (without mod_tiles because I'm 
using custom python rendering script) wich gives the best result so far.

But it looks like I might start having problem with mobile phone company using  
shared IP pool to NAT their clients 

Are you using other tricks ? blacklists ? download patern matching ?
thought for the long term ? 

PS: I haven't found a dedicated "rendering" mailing list so I hope it's okay 
to use this one
