I almost fell for this just today. I had a lady with no profile pic or info contact me about a patio chaise lounge I had up for $45. She called herself Demetria and said she was on travel but was buying this for a cousin. Same as your situation, she wanted to send me a cashier check and then have movers come and take the couch. She also wanted me to take down the ad to hold the lounge for her. Which I did. I unfortunately gave her my contact infor for the check before realizing to check google for scams. And sure enough I was directed to this forum where I find to my consternation that this is an oldie.
I feel about as stupid as a person can feel. I tried her number and got no answer. I texted her to not send the check because I know its a scam. I haven't heard back from her so I hope that is the end of it. I just feel so foolish to have given her any info at all! Of course now I see all the red flags: No profile, no interest in the actual lounge details, a strange insistence to take down the ad. Please be smarter than me and do not engage anyone that wants to send you a cashiers check or other payment!
