deino is currently listed as an ambiguous tag due to the fact that deino_(pokemon) exists and maeda_koutarou's online pen name is Deino. I'm suggesting that maeda_koutarou be updated to "deino_(maeda_koutarou)" and that deino_(pokemon) be updated to just "deino".

Seeing as not everyone knows how to utilize the artist wiki URL search, using "deino_(maeda_koutarou)" lets casual users find the artist's posts using the search bar's autocomplete. Additionally, using "deino" for the Pokémon is consistent with tagging other Pokémon, where the _(pokemon) qualifier is only used when the creature's name could be confused with an actual object (such as golem_(pokemon) and kabuto_(pokemon)).

I agree that maeda_koutarou's tag should be moved to "deino" plus a qualifier (I don't have an opinion on what the qualifier should be). howto:artist does say to prefer real names, but if the artist goes by their pen name everywhere, it would be a lot easier for those interested in their art to find it on Danbooru if we use their pen name too.

However, I think the pokemon's tag should remain as it is. Both tags should have qualifiers. In this case, rather than actual objects, the creature's name could be confused with the artist's name, and vice versa.
