how do we get rid of a griefer on the sim but it is not on our land?

Depends what you mean by griefer.

If its those self-replicating prims, you can submit an AR by clicking on Help button in your viewer. Check the box to include a screenshot of what it is that griefs. If it isn't removed right away then you could talk to the land owner and ask them to remove it and have an auto return set on their land.
