Sorry for not being clear, there is no way to do what you’re trying directly in the browser because we do not make the game pages available for fetching cross domain.
Ah, I see.
Getting slightly off topic now and I don't know if you're informed on this at all but do you have any info on why filtering hasn't been implemented?
It's been 6+ years now and aside from the ?exclude= thing people have consistently asked about it pretty much every year since. Does the backend just not support it? Is it low priority?
