I am also a business angel, funding people's things ever since 2004. One of the reasons I bought the castle is that people wanting to have funding can come there and make their way to my presence. After some time, I may discuss with them about financial cooperation. Such deals have already been done on these "castle terms" and results are expected to be announced in this month.
This is the way I want to make business and yes, many try to approach me via other channels and start communication by asking money, a loan or whatever. I try not to be rude towards them but the answer is "no", because there is no way for me to evaluate the other guy that way.
I am fine if you don't want to come to my castle but that is the necessary condition if you want to deal with me. Good thing is that world has millions of people with more money than me and you can ask them instead.
