Seriously, I don't like knots. Probably controversial, but there needs to be some way to blacklist them. Not all knots are on a dog penis (such as with lots of drakes/drake characters), so it's not like I can just say -canine_penis. I don't want to waste search space by blacklisting knot AND canine penis. Sometimes I genuinely don't give a rat's about it because lots of good art has a knot, and it usually isn't the main feature (okay, maybe only *sometimes* it isn't the focus). But if I don't want to see it I can't just blacklist it because it still shows up. How hard is it to just type 4 extra letters and a space into the tags when you upload?
Edits for clarification because even though this annoys me I don't want to sound like a dick.
Edit: removed the swear because again, I don't want to sound like a humanoid_penis.
