In 2016 I wrote a small Android app, that is making use of the Wikipedia ActionApi.
Due to legal considerations I am currently trying to take down the app.
It’s not available any more in the Google PlayStore, but there are still installations out there.
That’s why I want to make these installations unusable by deactivating all backend services, that the app is using.
Unfortunately the app is (partially) directly communicating with wikipedia servers and not via a proxy under my control.
The app sends a special User-Agent HTTP header with every request to identify itself.
Is there any way for the Wikipedia-Api team to block requests from this app?
Who would I contact?
Thanks for your help!
