The latest Travian servers have a limit on the amount of resources that anyone can farm from a village that appears to be accessed from the same IP of the farmer. This means that currently you can't farm too much from another account that is using VilloFetch because you both appear as coming from the VilloFetch server.
A possible fix for this is the use of public anonymizing proxies. This will be the next VilloFetch feature, one day...
