I was referring to the fact that BTC address history is public and not really as anonymous as some think. I didn't mean to infer anything else. I wonder if I google all the addresses that are published if any of them will turn up in website footers or thread footers as donation addresses? Or... if I run a competing exchange and I search my DB for all those addresses, I wonder if any of them will come up? 
That is why I said you would just create an extra address to use just for the public list.
With bitcoin wallets, you can have multiple addresses and use them for different things.
If you want the info to stay private, create a new address (that has no history), and use that.
