What it is

Operated by NICT, Japan's national information and communications research institute. The collected data supports AI research and, per the operator, is also provided to third parties including commercial companies.

What blocking it costs you

You are excluded from a national research corpus and from the commercial redistributions of it. This is a dataset-shaped block: one refusal, many downstream effects.
