It is mentioned that statistics cannot be retrieved in bulk, however the publications about population, unemployment (and pretty much everything else) on StatBel (Federal Public Service Economy) can be downloaded in bulk.
There is also a negative score for the licensing part.
Regarding the one dataset "GDP" on the National Bank site, I'd argue that they can be retrieved in bulk (one can download them) although indeed it is mentioned that you should not download it systematically
I'd say this boils down to "fair use" of the service, because many websites will block traffic anyway when one user impacts the server infrastructure, even if it is not explicitly mentioned in their policy....
Now, the GDP is also published on the main website of the National Bank, under https://www.nbb.be/en/publications-and-research/employment-statistics-trends/summary-tables/macroeconomic-situation
(download at the bottom) which carries a slightly different copyright notice.
If that is not acceptable, the GDP dataset can also be download for free from the Federal Planning Bureau, which does not impose this restriction http://www.plan.be/databases/PVarModal.php?VC=MODRESV&DB=MOD&lang=nl&XT=1
In addition: the reviewer explicitly stated that both the population data (on statbel) and the GDP data (NBB) do have an open license.
- please change the negative score on "openly licensed" to positive, as the reviewer explicitly indicates that the data is available under an open license
- please reconsider the negative score for "bulk download", given the additional info above
