1) When a user shares a ES post (see attached) on FB let's say, it only shows my website info not the actual scraped info from that post (like a share from a browser would)..how can I change that?

The reason why you hitting this is because Facebook do not have the permission to access your Easysocial post, you can do a simple testing here, try open this stream post in public area without login -> https://hakisaki.com/community/stream/item/2962 , you will notice it will redirect back to login page.

Because you have enable "Lockdown" mode from your backend Easysocial settings, in other word, public user will not able to view any stream in your Easysocial site.

To fix this, you have to consider to disable this lockdown mode option from backend, so Facebook can crawl your Easysocial stream content as well.

2) Twitter share doesn't scrape any type of pic/info of the post and just shows a link..can that be changed as no one really wants to just re-post/share a link

Is it possible provide us one of that stream URL which you mentioned, so we can test share to Twitter social network?

By the way, do you want to disable this repost and share link from the stream post?
