That's not necessarily working for me.
I'm currently running the bot and I've logged into buddyauth. It's showing that my key is active, but I have no sessions currently active, so there are no sessions to kill.
Same thing happens to me so try this, I found that if I change the "region" up in the top right corner on the "Buddy Auth Portal" page to the "best latency" it changed from NA to Europe (I am not from neither of these places) and now it shows the session to be killed now.. so give that a go.
