My ex once got contacted allegedly by the actor Stephen Amell claiming to be offering him a job writing scripts for his show Arrow. I called it from Day One that he was really talking to Stephen SCAMell - why would the lead actor be handling the hiring of writers himself, without any involvement from the actual production team? Why would he do it by messaging strangers on Facebook after two minutes of conversation - how could he know from that if my ex could even write?
My ex was having none of it when I tried to bring up the possibility of a scammer, sending me screenshots of the conversation to try and convince me. If anything, I was even more convinced it was a scammer, because Mr. SCAMell was asking for iTunes cards. The problem was, the weekend in question, the real Stephen Amell had tweeted a rant at Bank of America because he was having problems using his credit card in Istanbul, so my ex thought he was genuinely in need of funds, and he sent the cards. It didn't matter what I tried to say, he wouldn't believe me.
He got to the stage where he stopped telling me about the scammer. I was trying to find the profile in the hope of getting it taken down, told him I'd reported a few fakes - he thought that the ones I reported were fakes but he was talking to the real one, and repeated this to the scammer. Mr. SCAMell said something like "haha I'm aware of the situation, but thank you for letting me know" - however, he didn't like the fact that I was looking for these profiles, because he then told my ex that I was only saying he was a scammer because I didn't want my ex to succeed.
It escalated to the point where I had my ex panicking at me because he had waited in all day for a package containing a contract, a script for Arrow, and diamonds (?) which Mr. SCAMell wanted my ex to look after for him, and the parcel had got stuck in Thailand until he paid an excessive amount of money to customs. The scammer had sent a badly photoshopped invoice which was about as convincing as something my then-two year old niece could have produced with some paper and crayons. He was all set to ask his family for a loan until I talked him down.
I thought I'd got through to him that it was a scam. Unfortunately, the comments about me not wanting him to succeed stuck with him, and for ages afterwards he was (probably still is) convinced the dude was genuine and I stopped the job offer because I didn't want to be left behind while he made it big. Arrow used to have special episodes at Christmas, and when that year's aired he kept going on about what if that was the script he was meant to write. While there was more to it, it was the beginning of the end.
Best thing to do is stop engaging with whoever this is.
