BUR #18682 has been approved by @nonamethanks.
rename strangulation_furrow -> strangulation_mark
create alias ligature_mark -> strangulation_mark
Strangulation furrow seems to be a weird compound term. A Google search returns 35,600 results, mostly of a band by that name and pages which mention both the terms "strangulation" and "ligature furrow" (the actual name) but not "strangulation furrow". If you narrow it down with quotes, you get just 2,260 results. On the other hand, both "ligature mark" and "strangulation mark" return upwards of 1 million results. Since "strangulation mark" is the more intuitive name, I propose renaming this tag to that and using "ligature mark" as a utility alias in case someone tries to search by the technical term.
Edit: Fixed a mistake, changed the implication to an alias.
