This weeks Mishpacha had an interesting article regarding something similar.
Someone once gave a larger than usual sum for tzaduka (accumulated masser), did not take long for people to start knocking on their doors requesting money and appointments.
I had the same thing, after donating to a cause, I made it to the list. Each night I have rabonnim and gabaim demanding to sit with me for just five minutes, it always turns into some 30/45 minutes.
I don’t have the time for them.
Besides that whatever I pledge, they start arguing that I have to give at least xxx amount of dollars.
I really don’t know what to do about this.
