Is this even a real Plugin?

Signed up for the $1 for a huge number of images deal. Billed 6 bucks 30 days later and am told that even though I only have a few dozen images on my entire web site, I used thousands of images. Huh? Scammer…I am a neophyte, admittedly, but I don’t think the app does anything except infiltrate your system. I notice absolutely no difference with or without the app. That says a lot. We are talking a few dollars here…but I wouldn’t mind a few dollars from a few hundred people every month for doing nothing.
