Facebook has it's issues, no doubt. However, the issues you guys describe are easily remedied by going to your settings and managing your profile.

Mine is locked down tight, but I still get pictures of the grandkids which is my primary desire.

I also use it to participate in three different Randall knife groups on FB. They are closed groups, so no spamming. They are pretty active groups and are easy to use.

If you adjust your privacy settings, you can block alerts and notifications and limit who you choose to see your activity.

It's an easy fix..... 5 minutes.
