Three kinds of wrong language partners. These are the types of people whom you do not want to be your language partners.

Three kinds of partners in which you are going to waste a lot of time and energy. 
The first: “Collector of partners”: They have many partners and never answer your posts.
Second: “Ghost”. They act as if they are going to communicate with you,  and again they dissapear.
And third “Interviewers”: They ask you a lot of questions and never share information about themselves.

The solution for all three of them: Let them go !

Trying to communicate with somebody who is not in contact with you, does not make sense.
If you want to improve your second language you need to find a team that wants to seriously commit to  the goals that you are trying to accomplish together: That is,  improving your second language.
You didn’t have to let them become members of your team.  People who never answer, don't respect your time or don’t have a second language as an important priority. 

Select people who enjoy and respect you, with empathy and enthusiasm when going to fluency meetings. Find people like this, and you will share sessions with laughter and learnings.

----  I really agree with you, that was what inspired me to correct this post.  So many people on this site just collect partners, yet never help anyone out...  My favorite line is this.  I want to be your partner ( I have 125 already ! )  but, I just don't have too much time to communicate because I'm so busy...
