The problem is, as you start donating more money to almost any organisation they start doing things that straddle the boundary of allowing you to audit that your money is being used efficiently, making use of your expertise, stroking your ego, polishing your public image, and soliciting further donations.

For example, inviting you to receptions with free drinks, providing chances for you to meet the people you're supporting, giving you tours where your guide tells everyone you visit how very powerful important you are, asking your opinion on proposed initiatives and so on - right up to naming buildings after you.

Needless to say, cashing a check you get from Jeffrey Epstein in the mail might be OK - but if you've built the Jeffrey Epstein Building you've got a PR problem right now.
