When you are sitting for another player's account, you may be tempted to push their excess resources to your village. It certainly would make sense since you're spending time making sure things are alright in the player's account. Why not a little reward, right? Even if you follow the pushing rules, you'll still be violating something.

The Travian rules state that if one or two players are sitting each other they must trade resources on a 1-to-1 basis. For instance, if Bob is sitting Jon's account, Bob can go into Jon's account and send himself 10,000 clay, but only if within the next 24 hours he sends 10,000 clay/wood/crop/iron from his own account to Jon's.

This rule also applies within the marketplace, so be careful. If you're browsing offers that are on a 1:2 trade basis or 1:1.5 basis, you need to make sure that the player you are sitting for is not the one making the resource offer on the market.

The multihunter has a screen within his/her account that calculates the resource transfers between sitters. If there is a discrepancy greater than 1:1 between two accounts, the overflowing balance will show up in bright red.

If you are ever unsure of the resources you have transferred with your sitter, send the MultiHunter a message and ask him to look up your account - I wouldn't recommend doing this if you're running multiple accounts unless you want to get banned for a completely different reason.
