Unfortunately almost every game site we know of has something like the following in it's user agreement (this one is taken from ING):
E. Limits on Use of the Services. You agree not engage in any of the following: (i) use any automated means, including, without limitation, agents, robots, scripts, or spiders, to access, monitor, data scrape, copy or transfer any part of the Services or the Registration Data or other data of any User (whether individually or in the aggregate);...
(...and just because they have a typo in their agreement doesn't make it any less official...

)
We've addressed this before on the forum - we don't really know how to work with this. We do have IMDb in DVDpedia which isn't quite legal, according to their website but it is still beyond me how facts can be copyrighted... That's why we included the Links section in Gamepedia so that you could link to any webpage and access it again through Gamepedia but you wouldn't actually have the data on your computer, i.e. no user agreements would be broken.
We'll keep working with this but for now this is probably how it's going to be...
