I too have encountered this problem: every time I try to post on Facebook via the Nextscript API (using session login), Facebook has been blocking my account and forcing me to change my password for several weeks.
Today, I took my courage in both hands and recreated the Facebook connections for all the pages and groups I had, but using Username/Email this time (it’s not possible to change the login mode by session or by Username/Email without having to recreate a new account). For the moment, I’ve made 2 tries and Facebook hasn’t disconnected me yet.
