Whether the stream is gone, or you just stopped following.

In the cases of deleted streams, they generally have a good reason for being deleted. Sometimes it's an owner who decides to delete the stream either due to little or no traffic, or they just don't want the stream anymore. More often or not, a Community or Global Mod deleted the stream because it was in violation of ToS, and in that case, the images were most likely unfeatured or deleted anyway.

Waiting on the Globals to nuke it.
