Is Facebook running their experiments again?

I have a facebook account but i am not an active user. I have couple of groups i am a member of and one liked page. I sparsely check them, let alone post or interact with the platform.

Since friday(?) i have noticed my feed is full of gay and lgbt content. I have reported couple of pages and blocked few more but it just never stops and i see nothing but gay pages.

Is facebook running some experiments before presidential elections or wtf is going on with this degenerate company?
