Are you a Linkedin Group owner or manager for years?
#PeopleLoveDesign was not used on Linnked in back in January 2018, so I advsied a design team to use as their unique hastag.
I was posting something I thought was important. So I posted in as many group as I thought the post was relevant. But one ore more members of any of the groups' I'm a member of, flagged my post.
