The closest similar thing I can come up with is Jodel, but I'm not sure if you'd find any students from there unless maybe if you paid for an advertisement. There's also vauva.fi, but it's typically used by middle-aged people, and suomi24, but I don't know how popular it is today or how seriously people would take your message there because I haven't used it myself. Facebook might also work, but teenagers have escaped from there to Instagram and Snapchat so if that's your target group, it's no use.
But you could use all of the above to chitchat to practise Finnish. (Although be warned: Jodel is a popular app with lots of users, discussions about what's happening in your city at the moment, subcategories with themes that might interest you, and threads with genuinely nice and helpful people, which all might sound good to you - but there's also lots of trolls. If you go there, don't take stuff too seriously.)
