Tags do not make them blocked, I think you meant that they normally would be blocked by the setting, because they are marked in their meta data as adult.
You are concerned that there might be tags one does not know what they mean and suddenly they unlock the adult content. Eroge is the only one I can think of. For that matter, even nsfw and other common adult tags, since we are talking about juveniles and at that they might not even be fluent in english. Otherwise, the tags are what adult games use to make them visible for people looking for that content. And a few explicit tags. The surprising thing is more, which typical adult tags do not ignore the setting.
