Exactly my experience a few years ago (it not working is directly related to how little I use Facebook today). You might stop getting stuff from that specific page or account or whatever but you certainly continue to get related stuff.

I get the ads about Warren Buffet’s (or other money celebrities) investment group or whatever. They are usually WhatsApp based pump and dump schemes for Chinese stocks.

Facebook somehow can’t detect these obvious scams, but somehow they have no problem pushing them to me after I looked into it when a fried almost got taken.
