There have been many changes in Facebook policies about posts sharing for the last two years.

1. If you are sharing posts in groups and you have just signed up on Facebook, they will block you immediately.

2. If you are sharing posts that have some spammy picture or text, they will block you within 24 hours or your posts will not be visible to others. Never upload pictures from google, it will be regarded as spam.

3. If you share the same post from multiple accounts using the same device, they will restrict you from all accounts for at least one week.

4. If you continue doing the same after one-week restrictions uplift. They will block your accounts most probably.

Safe Method

1. Do not post one post in multiple groups at the same time, do postings in some intervals.

2. Do not share same post using multiple accounts on the same day.

3. Use one account per day to share 10–15 posts at different intervals.

4. Make sure your posts are free from spammy text and images.
