Yes this is a problem i got a simular message when all i have was an link in my post and i see it all the time on steemit it seems that the same rules don't apply to all go through this all the time Pixabay is recommended free picture site of steemit i got flagged for using a picture from Pixabay the harrassment that is given by whales makes steemit a site that is more in favor of the big and craps on the small to medium user people say bitconnect is a ponzi pyramid scheme but steemit feels the same way where the early user can release BS post and make large amounts on money while people who actually post valuable content wont even get many looks on their post.
