Authentic sharing can often include the following along with posts on other topics and conversations:
1. Here’s something I read that was important to me and why, followed by conversation.
2. Here’s a link to something beautiful I love and why.
3 Here’s something I made/wrote you can see/read for free! (Usually with one photo and a link, possibly Etsy).
Spamming:
1. Make money with Affiliate link
2. Join my paywalled content!
3. Nothing but links to other social media.
4. Nothing else.
