I think this happens when you don't choose your language partner carefully. There few points have to be covered in her/his profile such as: his/her targets to join this website and learn a certain a new language, the details provided in his/her profile, and his/her activities within the entire discussions. I think these points greatly show how serious, and motivated he/she is. Finally, you can measure how much perfect he/she can share studying and practicing with you. I mostly apply this strategy before communicating with someone, and it helps a lot.
I'm not woman, but I have no interest in girls haha
So, would you like to talk?
