Duolinger isn't only a beneficial resource for those looking to pick up a new language.
It has also become popular with language aficionados. However, sadly, it seems that even this cherished platform is not exempt from the notorious Rule 34 phenomenon.
There are countless people found that Duolingo® + Rule
34 combo exist out there. It could come as a surprise, but ostensibly, there are actually user-generated artwork based on characters of Duolingo that adhere to the infamous guideline stating that "if it exists, there is porn of it."
