The analogy to dating is problematic. Such a strategy is indeed effective for dating, but feels mercenary or even sociopathic to most people. Making the analogy raises moral issues that aren't relevant to fundraising.
Every human interaction is just analogous to dating, because human interactions are based on interest and the whole thing is called social dynamics. Be high value and wanted and everybody wants you, be desperate and low value and nobody wants you.
In dating, it is sexual interest, in business, it is monetary interest , the underlying principles are the exact same.
