Prohibit owners or corporate officers of a for-profit business to do business or serve as officers or board members within tax-exempt charity organizations that they themselves established to benefit from illegal tax write-off incentives and profits from community contributions.
For Example: Any individual can establish a tax-exempt charity that then hires a for-profit "fundraising service" based on commission or deferred pay from the amount raised. This individual can then collect a huge amount of the contributions by writing himself a bill for half of that amount as a "fundraising cost" or "program service cost" and legally pay himself that money.
STOP these unethical business savvy people from forming these "hybrid for-profit/non-profit enterprises" and form stricter IRS rules.
