You may have a point and we will see what Mark thinks. Yes, Vera is right, we have to choose our tutors with a little care. There are native speakers offering services that might help some people but not others.
I suggest to make a special site for tutor settings. That would make it more clear.
Today I saw a profile with horrible English, and the settings were “correct English”. The member signed up 3 or 4 days ago.
We can’t really prevent people from tutoring in specific languages short of having an approval process. For the most part, users will have to use the information they have available to make an informed decision about which tutor to try. We did add the Native Language indicator and country flag to help with this in addition to the writing corrected and conversations hosted numbers. We have not heard from members disappointed with the tutoring they have received so we have to assume that the system is working. There are going to be people offering to tutor in languages they are not native in.
