The makers behind documentary Cowspiracy want Instagram to fight the exploitation of farmed, hunted, and fished animals.
The platform recently launched an initiative to protect wild animals.
Whenever certain tags - including #slothlife - are used, a pop-up appears on the screen saying: "Animal abuse and the sale of endangered animals or their parts is not allowed on Instagram.
"You are searching for a hashtag that may be associated with posts that encourage harmful behavior to animals or the environment."
According to a spokesperson for Instagram: "We are committed to fostering a safer, kinder world both on Instagram and beyond."
But the Cowspiracy team would like to see the scheme go further.
They took to Instagram to comment on the plan in a post that said: "Now imagine if they did this with hunting, fishing, animal agriculture..."
Many users agreed - Theroseanthology said: "This major disconnect has always been mind baffling to me. People love their dogs but eat a variety of other animals?
"I ALWAYS tell carnivores this: Some cultures use dogs the same way you do cows and other cultures see cows the way you see your dog.
"How are your views above those who see differently than you? The disconnect from the bigger picture is heartbreaking [sic]."
