Artist's name tag confusion

So, the artist holy_pumpkin goes everywhere by the name emmmerald or some variation of it:
Twitter - emmmerald_ / Emmm_
Pixiv - emmmerald / Emmm
weibo - emmmerald_ / 用户Emerald_Carbuncle
tumblr - emmmeralddd
lofter - 用户emerald_carbuncle

And I remember seeing their works under emmmerald years ago, so, where did "holy_pumpkin" came from? Also, maybe it should be changed, but I'm mostly curious about the pumpkin origins.

Searching the tag in the forum, back in 2014, their tag was originally xelwyw1103, but the name they had on Pixiv was "ホーリーパンプキン", which got romanized as Holy Pumpkin. See forum #96121 and forum #96124.

Since their current name on all sites is totally different from their danbooru tag, it should be changed. I posted an alias request in the thread, but an admin will have to approve it.

Thanks for the info and for forwarding it to be changed.
