Scammers target the vulnerable. And if you are not in the right space of mind, you can be easily manipulated.
Saying that, if you think Brad Pitt is actually messaging you, and asking for money whilst declaring undying love, then you need to have a word with yourself.
I met a guy years ago, new on the dating scene. He seemed a bit sketchy, but at the time I was only looking for fun, and he was good on the sack (yes, shallow!)
Anyway, he told me he was a barrister. I didn't think much of it, as I dont need a barrister. He did ask for money (small amounts) a few times, but he always paid me back.
He was going through his own divorce, and I was a chronic people pleaser back then, so when he asked me to be a guarantor for his rent (thinking he was a barrister), I had agreed, as there was never any red flags with money and not getting it back.
Months later, I was getting phone calls from the letting agency asking for payments. Apparently, this man was now in jail, for fraud (he was in fact not a barrister and had got loads of women to send money for divorces to the tune of 13k) and he owed the letting agent £1k.
As a guarantor, I had to pay up or be sent to court. I also had no way of contacting this man as he was in jail.
8 months later, he was released and ended up at my door, and paid me back half there and then. He said he would give me the other half the following month, but I told him just to post it through the letterbox. It never came, and I deleted and blocked all ties to him.
Its the closest I got to a "scam", and I was really quite vulnerable at the time.
