That’s a tough one. There’s likely a lot of testing going on. Like I know we make keypairs all the time to test. Probably many other cases as well. First thing that comes to mind is to widen the band of w0 to m0. Like consider anyone that doesn’t stay for at least a month a non-user and see what that drop off rate is. It’s a blunt idea. Hoping your convo with @Pip the WoT guy is more fruitful.
