You can steal from the islands of your neighbors in Island Paradise. You may steal from a maximum of three harvestable features on a given island per day. Trees, crops and animals can all be stolen from.
Some players do not like stealing. Developers have stated that this is one aspect of the game that will not be removed.
Once an item has been stolen to the maximum, other players will see the balloon that appears when they hover over the object "Nothing left to steal". The limit will be reset at 12 midnight Pacific Standard Time (PST), the timezone that the Meteor Games office is based in, not according to your computer, where you live, or anything else.
Example: a crop has 6 harvestable items to start; therefore only 3 of them can be stolen
Note: in the case with Grapes and Dragonfruit. Thieves can steal enough to cause a profit loss, while not going over 50% of the original crop count.
Dragon fruit cost: 45c to plant
harvest was 2 fruits worth 32c each
Grapes cost 65c
harvest is 10 grapes worth 10c each
Not all players are opposed to being stolen from. Some players leave crops available to be stolen from as a way to help their friends gain money and experience in the game.
Some players have taken to placing a white flag, a decorative feature sold in the Island Paradise shop, on their island as an indication that they do not wish to be stolen from. This practice is not recognized by the game developers and imposes no physical block to stealing.
Some players take exception to the stealing element in Island Paradise and have implemented a zero tolerance for stealing, removing those who steal from their island. Others implement a lesser form of this by politely asking that their neighbors please not steal from a certain prized animal or tree. Neighbors have no obligation to follow their requests.
You can read about that on the Protective Features page.
Due to Facebook removing the ability for applications to send notifications, there is no longer a way to get a notice if someone has stolen from you. You can, however, hover over your crops, trees, or animals to see how many of the item is left ready to be collected. For example, a cow may have 4/4 Milk to collect. If the someone has stolen from you, the cow will say either 3/4 or 2/4.
