It seems 'exclude' does not work as expected

Describe the bug

I am trying to run the following command:

$ node_modules/.bin/blc "https://hydra.family/head-protocol/" -r --exclude google --exclude github --exclude 'nix' -v

but I still see broken links reported here:

To Reproduce

Just run the above command, the web site is public.

Expected behavior

I would think the file://nix/... links would not be checked.
