Still playing or not?

[Carolinekay19]

How can you determine if a player is still playing?

You can't. If no visits to you within whatever you decide is a reasonable grace period, it is perfectly fine to delete them. To be extra polite, you can leave a post on their wall saying if they ever come back and visit you, that you will re-add them. By leaving that final post, they can easily come find you if they are interested.

Keep a record of those that gift u, then u know at least their active.
