Facebook and other social media.

I originally posted this in my due date board but thought I could add it here too!
Let me start off by saying I hate Facebook lol. 
But I have one. I had deleted it and lived "off the grid" for a few years but then I moved to a different province (like a state--I'm Canadian) and having one does make it easier to be in touch with others. I enjoy that part of it although some people, imo, are way too public with their lives but whatever... Their choice! If they annoy me I delete them or I block their posts from my newsfeed. No big deal. This is not a judgement post. 
My husband and I are very private. We actually have not even posted about our pregnancy (I am almost 37 weeks lol) but of course family and real life friends know. He has lots of concerns about making our children vulnerable publicly if we were to post lots of pics of them. Among many many other concerns we have but that is number one. 
We recently texted our family our feelings. We did say we will post the odd pic for special occasions and are ok with them sharing those or copying those OR even posting one of our child and them together on their own. We just don't want anyone uploading 80 pics of our kid in a year, for example. I think that is more than reasonable, personally.  
But still it's crazy to me we feel we need to even share this... 
We did clarify that we are not limiting them taking pics or printing pics of our kids. We plan on taking and texting close friends and family lots ourselves. We are ok with them texting them to whomever just not posting a ton publicly online. That's all. 
Now I'm not even referring to something like naked pics of children on Facebook. To me it's common sense that those should not be posted yet my very own cousin--who I do consider mature and intelligent ( and others I've seen over the years) posted completely naked pics of her 1.5 year old daughter. Innocent? of course! Adorable? very! But in a public place where you don't actually own your pics once they are posted.. And friends of your friends can see a stranger's post.. Even when you do make things "private"-- newsflash nothing REALLY is. To me? -- Scary!!!
Am I alone in this? Did anyone else feel the need to "put restrictions on public picture posting" with their family? Does anyone else feel like social media is becoming too much and some people live life "too publicly" and potentially are putting their children at risk and making them vulnerable? Do we actually have the right, even as a parent, to post that many pics of another person... Even one that is "ours"? 
Just curious if other parents share my sentiments. Thought this could be an interesting debate.
