Of course it can be disabled, and very easily, too.

At the end of each contract, immediately below the "Collect" button, is a checkbox labeled "Publish to wall", or other words to that effect. Uncheck the box, and no notification will appear. This box is always checked by default, so you must uncheck it every time you collect a contract.

This is a change in design, not in function. Previously, you had a choice of two buttons: "Collect" or "Collect & Publish". The new design accomplishes exactly the same thing in a slightly different way.
