Newbie Question: about copyright tags that imply copyright tags.

Is it reasonable to make BURs that imply copyright for ex. eroge studios based on game copyright tags? (such as kamidori_alchemy_meister implying eushully)

company copyright tags generally are only to be used for references to the company/dev, or company connection posts

not for literally any post for an IP by the company

Hmm, okay. I got the impression from howto:copyright that they can be added to anything that is related to or from the company/brand/series.
