Hello,

in 2016 I wrote a small Android app, that is making use of the Wikipedia ActionApi  to search for articles at the current location of a user.
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:

tagorama/v1.0.0.283-release (http://tagorama.rocks/; info@tagorama.rocks)

Is there any way for you to block requests from this app?
Who would I contact?

Thanks for your help,
Frank Wunderlich
