Yep. And despite the tendency of some folks to rip on people who let that happen, it's actually fairly common on a variety of sites: Amazon, DreamsTime / similar image asset sites, an online newspapers subscription, etc. Even month-to-month can fly under the radar if you're not paying enough attention.
You should ask this over on the Recommendations and Identification forum, specifically set up for questions like these. FFR, site rules now say that this type of discussion should not happen in a game's thread (see Rule #2.4). Just FYI.
