New user here, my apologies in advance if this is not the right place to post this question; I scoured the forum first for anything similar-sounding, I promise.

In summary:
-I personally spent dozens of hours tagging dozens of 'egg_insertion' type images with 'oral_ovipositon' so that I could blacklist images like this one: https://e621.net/posts/2278295?q=egg+oral where characters are having eggs shoved down their throats.
-However, I very much still want to view images like this one: https://e621.net/posts/2277981?q=egg_insertion where eggs are being inserted into holes other than the mouth.
-I authored the wiki entry myself. I readily admit I may have messed it up somehow, I am novice, after all: https://e621.net/wiki_pages/28616

I am certain that in April of 2020 (after the great server migration), the 'oral_oviposition' tag contained at least 80 entries - and over 60 of those were my personal effort to ensure my blacklist was accurate. However, as of 11th of June 2020, the tag contains only 22 entries. I can only assume some more experienced tagger removed the tag manually from literally dozens of images. I don't care why, I'm not looking to play any blame games - I just want to know this:

---To avoid this erasure of effort in the future, what tag /should/ I use to differentiate oral insertion of eggs from anal or vaginal insertion?---

I really, REALLY want to hear from other site users more experienced/knowledgeable than me, who can weigh in on this issue.

Edit:
Update, I discovered this specific wiki entry that basically answers my questions: https://e621.net/wiki_pages/26514 However, the 'see also' section leads to several un-created pages such as 'oral_egg_insertion' and similar. I also discovered the family of tags 'egg_in_mouth' and similar, and 'egg_from_mouth' and similar. Since 'oral_egg_insertion' overlaps with 'egg_in_mouth', is an alias or implication in the offing here?
