Duolingo 

A catfish and a kidnapper who disguises as a cute, friendly green owl. Slowly this green owl will keep manipulating and guilt tripping you into doing things you otherwise would never do. It starts with learning a language... but it ends with something way worse, and once you enter, there is no way out. Duolingo will literally kidnap your family to keep you under his wing.

Me: Duo you can't keep ruining my life like that!
Duolingo: Shouldn't have missed that Spanish lesson *evil laugh*
