Public records are published based on certain demand assumptions.

If a real-world demand for, say, some GIS data is hundreds of requests per day, then a crawler that comes in with hundreds requests PER MINUTE will obviously stress the infrastructure. Adjusting infrastructure to cope is not an instant process, nor is it a sure thing to begin with given all the budgeting formalities. So your "civic duty" will ultimately result in destruction of these services, because they simply don't have the means to deal with such thoughtless activism.
