What can I do to stop this?

[winsock]

Or you could just get off your high horse and stop telling other people how to play the game and use their time. That would also stop the cycle. And, that's also what I've been saying this entire time.

I will use your own terrible logic against you since that is what you seem to live by:
You telling me to stop calling you out for leaving is telling me how to use my time.
This makes you a hypocrit.
Therefore, I am justified to tell you how to use your time.

^ if you consider this logic bad (it is bad), your justification for abandoning your duty finder parties is also bad
