The quote of mine that you used in your last post was one that I made to someone else. If FB are detecting that it's a CPA offer I take it that you are redirecting traffic directly to the CPA landing page rather than to a page on a site that you own?
If you're redirecting traffic directly to the CPA offer page then it's probably a FB bot that is recrawling the link on your FB post and seeing that you're not redirecting people to a CPA offer.
Instead of doing that you could send them to a landing page on your own site where you can display your offer. If you are using WP for your landing page then you can hide the external links to the CPA offer from bots so FB bots never see those links.
