I'm a little surprised they're dropping the subscription model while many other sites have started to adopt it due to declining ad revenue. Especially on an image hosting site, as I doubt the click through rates are very good. (Yes I realize they probably get paid per impression, but typically lower CTR means the CPM is lower, too.)
So what are they doing to people who had paid for a subscription? There's no discussion of a refund.
I got a refund. They are ending all automatic payments.
Seems we all get the pro version for free and their new revenue model will be ad-supported.
