Since the data feeds seems to be "live" data, I'd like to know if there's a limit of requests that can be made to them. I'll be using the datafeed's data to display some informations into my website, and I need to know if there's any issue about making high number of update requests: Yes, I'll be caching the results, but I need to know a reliable timeout for it (server check interval for example, to avoid getting same data every request.)

So ... ?

A reasonable time interval for checking data feeds would be 15 seconds or greater. Servers typically will be updated every two minutes, sometimes less, sometimes more, but never less than a minute.

Please keep in mind, abuse of this feature by spamming requests will force us to suspend your account and/or blacklist the offending IP space.

That's why I asked. So if I set the cache interval to 1 minute (1 update/min), is there any chance to get blocked?

I think that would be fine. How many different servers are you planning on requesting data for?

Depends on the end-user # of servers... I'm working on a CMS for clans: each clan will need a GameTracker premium account to get GT's feed urls. After that they will need to register their URLs so the CMS will be able to display the collected data.
