I don't understand why people post images of text, rather than simply typing in manually the text themselves. (These prefabricated memes also often contain egregious misspellings - and I can do without them!)
In any event, I posted "Stop the Steal" (without the pound symbol - is that important?) 18 hours ago, and have yet to receive any notification / warning from Facebook.
Regards,
Well goodie for you. /s
