Spam Warning and 7 Day Ban from Facebook

Hi. In December last year I got banned from posting on Facebook for 7 days for a spam violation because I posted too frequently on my pages and groups. Since roughly around that time link posts on my large Facebook pages have seen a drop in roughly 80% reach. Normal photo posts without links still do very well link before. I feel like Facebook is reducing the reach of my link posts on purpose. Does anyone have any advice on how to solve this? Should I remove myself as an admin and post from the Facebook pages from a family member’s account who doesn’t have a spam warning from Facebook?

Thanks!
