Duolingo® is more than just a beneficial resource for those wanting to grasp a new language. It also has gained popularity among language enthusiasts. However, regrettably, it seems that even this popular platform also falls victim to the controversial Rule 34 phenomenon.
There are countless people discovered that Duolingual + rule 34 fusion exist. It might come as a surprise, but apparently, there are user-generated artwork based on characters of Duolingo which abide by the infamous rule that states "if it exists, there is porn of it."
