pyramid schemes

Sorry if im being annoying this was probably asked before on here but my fb is flooded with people selling stuff via pyramid schemes. There my family and friends. Im not the type to be up front so I usually try to be nice about it. when people message me about their stuff. But its SOOOOO ANNOYING!! and every day someone else joins lol. So far I see Rodan and Fields,Optavia, Army leggings,Plexus and Arbonne. Oh and Posh. Somebody messaged me today saying I won a raffle. I was excited lol I never win anything I have the worst luck ever!! and then she messages me saying I get a free gift with my next order🙄🙄🙄 I never even heard of the company somebody added me. And some of these people dont back off like legit!!! Occasionally my plexus friend makes me wonder if there is omething there. She claims she won a lexus, gets free touring trips, makes over 500k a year lol is it all lies and bs? anyone else about to delete all your friends😭😭😭😭
