We need to compile a list of common scams to protect ourselves 
I'll give you a starter list.. There are many variations on a theme but here are some i've run into over the last few years....
My ex has left me with cc debts/not paid the utility bills/not paid the rent and we are gonna be made homeless/taken all my money and I/we (me and my child) cant afford to buy food. etc etc etc....
I/my mum/sister (whatever) has a medical emergency......
My childcarer wants paying in advance for when i meet you, so can you PayPal me...
I need taxi money to get to you... 'I'll pick you up'...'No'... I cant cos...... insert a million bullshit reasons.
I want to buy some sexy, new lingerie for our first meeting.
Send me the £ and i will book the hotel for us. I get a deal (sis works there, or such) so i can get us a suite with walk in shower/sunken bath etc etc....
My car needs an MOT/service or fuel.......PayPal me.
You promised to look after me
My previous SD paid me £xxx per meet/per month (divide by 4 to get closer to the real amount....)
The £ you sent me didn't come through.....
If it sounds too good to be true/or it doesn't add up.. Then it doesn't add up.
eg: The girl tells you she is a lawyer/architect has a good career and earns good money etc; yet is aged 21.... If she is gonna lie to you on such a trivial matter; then she is a liar, pure and simple.
etc etc etc etc etc.... and on and on and on......
Ofc... the request for £ is always followed by the stunning sex she will deliver as a way of a thank you..
