Most of the attachment images are too small to see or read unless you log in, so they register and look around. Then they probably decide not to stay.
I don't get it either, yet I've seen it in every forum I've had a hand in. I've done something similar, I suppose. I know when someone recommended MeWe (a Facebook alternative) to me, I tried it and learned that I had already registered for an account there. Apparently, I didn't find anyone I knew there, or there was some other reason why it didn't interest me, so I never came back and then forgot I had even heard of it. But that was a case where I wouldn't know what was there until I joined.
