I almost fell for the scam a few years back of selling something to someone, they 'accidentally' mail a larger check than is necessary, and I send the extra back via wiring/moneygram, etc. Luckily I smarted up and was able to cancel the order at the last second and deposited MY MONEY back into my account.
So I don't like scammers. So here's what I did a few months ago (true story)
I was looking around CL one night at about 1am when I came across an '02 Tacoma that was obviously a scam. It was around $2k, with only 88k original miles, perfect interior, exterior, 4x4, etc. The seller had the whole schpiel about 'pricing it low due to her husband dying and her having to move cross country' or some variant thereof.
So I started off by texting her about 20 times, (copy and paste) saying, "You're fooling no one". I started getting phone calls from the number. She/he just keeps calling and calling and calling. I just kept rejecting the calls and sending the texts.
Keep in mind this is 1am. My wife is in bed asleep next to me and I'm sitting there giggling, phone on completely silent, screwing with this guy.
After sending the text about 40 times, I change it up to say, "Just ****ing with you, I'm interested in your Tacoma." I send this about 40 times as well. The scammer starts calling from a different number, over and over.
After honestly an hour of this, I send a text saying, "Oh, I'm so sorry I missed your call. Thanks for getting back to me. Some people on CL are really rude; they try to sell something, but never respond back to my inquiries. I'm sorry about the time as well; I didn't realize it was so late. " I send this only once.
Scammer replies back with, "I know! I hate that! I tried calling a LOT of times, but I couldn't get ahold of you! Unfortunately, I sold the Tacoma earlier today. And don't worry about the time at all!".
Me: "Ok, that's fine. Thanks again for answering. Have a great night!"
Scammer: "Thanks, you too!"

I see the Tacoma ad posted anew on CL the next day…
