It is sad but true that some people still fall victim to the scam emails offering thousands or even millions of dollars. Please don't get taken in by them. You can't win a lottery you haven't entered, or a grant you haven't applied for. Nobody that you haven't met is really going to send you £10million just for supplying your email address.
These scammers are all after one or maybe two things. Your bank account details and your ID. They don't want to add money to your account, they want to remove it.
Here is one scam I received just a few days ago:
"We are giving out a yearly donation of US$850,000.00 each to 100 lucky recipients. These specific Donations/Grants will be awarded to 100 lucky international recipients worldwide; in different categories for their personal business development and enhancement of their educational plans."
There is a lot more fluff and then a Hotmail email address. They even include the bona fide website address of a French charitable foundation. If you visit their website even my GCSE level French can tell that there is a message on there telling you about the scam and saying they only send communications in French!
It's sad but true that these scams continue. I guess they continue because every so often someone falls for them. Please don't be taken in.
