Is there a quick and easy way to prevent users from seeing and approving each other's tasks? I do NOT want to create a task list per user and would like to avoid setting up item level permissions / event receivers.
MSDN forums suggest turning on view filters and filter by [ME]. Which I think is a bit silly, considering that users can create personal views or use other techniques to go around it.
In SharePoint designer workflows, there is this option called "Only allow task recipients and process owners to read and edit workflow tasks" (which I haven't tried, but I would assume provides the functionality I need). This is a Visual Studio, SharePoint 2013 workflow however.
