Implicating smearing_feces → feces
Link to implication

Reason:

Smearing is the act of smearing feces on an object or person as a form of scat play, so it should always imply the scat tag as the scat tag indicates scat play.

Additionally, I'd like to request the following:

smearing_shit ---> smearing_feces
smearing_poop ---> smearing_feces
scat_smearing ---> smearing_feces

big -1 for this and the wiki changes you made. the term "smearing" is not exclusive to smearing feces. it can apply to smearing any substance. smearing_feces is the tag that should be used for this, not the ambiguous one that could apply to images where character is smearing paint on walls or cum on their body

-1 to this for what siika said, but while we're on the subject:

I feel smearing_feces (or other tag, if it's aliases to something, whatever) should imply the messy tag; it's inherently a messy thing after all.

Yeah, I can easily see making either of those two changes
