Tag's already part of an alias, hence why I just made a normal forum topic for this, but kyuuri26 and kakuteki11029 are the same person.
They've begun posting furry stuff under a new name on Twitter, possibly because they found work as a "designer" at a game development company.

I did notice that they deleted a few tweets since then, so if they're trying to keep up appearances, it might be better to use the new name. However, not everything has been deleted, so there's also a reason to reverse the alias.

if their goal is to separate NSFW from SFW and it's an intent of hidng, than the tags should just be mentioned in the artist wiki for both names, not aliased.
