The tag alias #62593 blush_line -> blush_lines has been approved.
Reason: Alias a less-popular singular (10) to a more-popular plural (23,496).
I am pretty sure they mean the same thing - a series of short diagonal lines drawn underneath a character's eyes, to indicate that they are blushing.
Usually the singular form is standardized, but in this case, the plural is a much more common tag. Also, as far as I know, these are almost always drawn as multiple lines.
EDIT: The tag alias blush_line -> blush_lines (forum #366925) has been approved by @gattonero2001.
