Thanks for participating, I have a busy week or two ahead, so it'd be impossible to handle this all myself. One important thing about this list is that all antecedent tags have zero posts, meaning they are all invalid and have been abandoned either by aliasing or by mass-updating; so there's no reason to create new implications for them.
The reason I requested this list from Albert and opened the thread is that, even though the tag is abandoned, the implication still exists. The implication itself is harmless, though useless, but it may indicate that somebody forgot to move the implication to the new tag when aliasing or mass-updating. So, first it's necessary to find out what happened to the tag, which might require some forum archeology; then check if implication is valid for the new tag. If it is, then new tag should have the implication, unless it already has it. After that, the old implication will be removed.
For example, genya_arikado is currently arikado_genya, and was moved about 7 years ago after discussion in topic #384. And arikado_genya has no implications, so it's exactly one of those cases why I've started this :3
What happened to adrian_fahrenheit_tepes is a mystery, though, since it's currently impossible to search for a tag through post versions, and there's no mention in forum either, besides unfulfilled request to remove implication in topic #10901.
