You might want to be careful because a lot of serious directories have protection.
Not something I'd bother doing on BOTW or something like that. Specifically, it's unlikely I'd do this on a general directory at all. More like old 'resource' pages on .edu's and the like, where they setup up pages of 100's of links in my niche.
