I love FB - Ill get that out there to start with !!
BUT I have only my close family as friends and my privacy is set as high as it can go so I'm not discoverable by phone number or email and my posts are not open to search engines.
I have just popped onto the Gransnet FB page and it would appear its open to all, no need for registration , unlike the actual Gransnet Forum where by you have to register.
I went in search of Gransnet Privacy Policy ( which of course I like many of you never read when we signed up ).
I also looked at The Terms of Use - and to use my Grandma's favourite term - we're buggered !
This is the passage that has scuppered any rights we thought we had ( I think)
By submitting user content to us, simultaneously with such posting you automatically grant to us a worldwide, fully-paid, royalty-free, perpetual, irrevocable, non-exclusive, fully sublicensable, and transferable right and license to use, record, sell, lease, reproduce, distribute, create derivative works based upon (including, without limitation, translations), publicly display, publicly perform, transmit, publish and otherwise exploit the user content (in whole or in part) as Gransnet, in its sole discretion, deems appropriate.
I too shall be a far more cautious poster going forward !!
Maybe a strike is in order
