At least they emailed you about it.

In my case they reactivated it for some reason and I had no idea for months until someone told me they saw my Facebook page.

I had just deactivated because I wanted to take a break from all the fake relationships, but I never really hated the company itself.

But now that I know this company just does whatever they want and doesn't care about the contract with their users, I despise them with passion. It's one thing to change privacy policy, but reactivating someone's account without permission when he clearly has deactivated is almost illegal.

I ended up completely deleting my account (that's different from "deactivating". It's actually all gone (hopefully)

I'm sure there are many people like me and OP out there. It's sad that people can't do much about it as individuals even when their privacy is fucked with.
