If (s)he is babysitting the player's account, taking stuff from them won't be difficult. (remove the wall def, increase tax rate, loyalty to zero...)

The question was how low do you have to be to do that to an ally?

To me, it depends on why the person needed time off evony. If it's something lame like "I'm playing COD instead" or "I have a big test at the end of February I gotta study for" then, yes it seems like account abandonment to me.

On the other hand if it's "my spouse had a stroke, hopefully will be out of the hospital soon," then I'd hope you'd extend some courtesy.

Now, whether you plunder and steal or just leave it to go to refuge...
