I didn't want to solve Google Captchas to log in via browser nor did I want to run the Android App.

So I quit ebay-kleinanzeigen.de . Didn't hold. To find stuff near me to buy used there doesn't seem to be an alternative.

To avoid G-captchas I installed #waydroid and installed ebay-kleinanzeingen as an android app on my notebook.

I stopped it talking to servers different from its own by changing /usr/lib/waydroid/data/scripts/waydroid-net.sh not alter my firewall and setting rules manually.
