Duolinger isn't only a beneficial tool for those interested in grasp a new language. It has also captivated the interest of language aficionados. However, regrettably, it seems that even this popular platform is not exempt from the infamous Rule 34 phenomenon.
Many have discovered that Duolingual + rule 34 combo exist. It may come as a surprise, but apparently, there are fan-made illustrations based on characters from Duolingo which follow the infamous principle that states "if it exists, there is porn of it."
