The tag alias #78543 latios4 -> shannon_shark_(artist) is pending approval.

Reason: I spoke with this person on Discord and they want to use "shannon_shark_(artist)" on e621 instead of "latios4". A few images drawn by her have already been posted under "latios4".

Don't forget to show your proof with offsite sources of the link, which can include a screenshot of your conversation where they tell you their preference.

Independently, this link can probably be best seen on their FA which has links in their Contact Information to accounts using Shannon Shark.
