re: Facebook is changing the rules for pages.

I have noticed that the reach on fb “shares” has dropped significantly. There seems to be an increase in pages downloading pics, then uploading to their own page and tagging, as a way around it.
I was excited a few days ago when I had a major site (100k+) “liked” my “Australian summer” pic and told me they were “sharing”… only to find they downloaded and uploaded it instead. It resulted in what appeared to be zero benefit to my page. Excitement turned into disappointment. I had previously purchased supplies at their Belmont store…but in future will support other businesses.
