Schengen visa and dating fraud

Dating fraud often involves so-called ‘red flags’, which are warnings that ensure that you have to be extra alert because the risk of fraud is very high. Examples are:

You have a date who comes from abroad and who speaks good or poor English, or says she speaks Dutch because she has followed a Dutch language course.
Your date seems perfect, too good to be true.
You will be showered with love and compliments in a short time.
Your date wants to move communication from the dating site to Whatsapp or email.
Your date makes you enthusiastic about a successful investment and encourages you to participate.
After some time in contact, your date promises to come to you in the Netherlands, but suddenly problems arise, for example, because it is not possible to obtain a Schengen visa, this problem can be solved by transferring money.
You are asked to transfer money to solve the problems for her, such as paying hospital bills, travel expenses, plane ticket or the costs for a Schengen visa that are higher than normal.
Your date says she’s going to apply for a Schengen visa but doesn’t ask you for any supporting documents, such as a form guarantee/accommodation provision.
You will be asked to pay a small or large amount in bitcoins. Payments can also be requested via Western Union or Moneygram. Usually the request is urgent.
You will be asked to deposit a guarantee amount that the lady needs to leave the country.
You are asked for a loan with the promise that you will get back the loan amount.
You may also be asked for money in other situations.
