Great. With this hasty move you removed every option to generate that vanity adress with provable "only we have the priv key" for them.
People may trust you here. Donations may be a small sums game.
But you might be shocked to learn that real business (tm) might not accept to have a funds accepting account where some stranger(s) have unlimited access to. I don't even believe that bitpay would want to touch this adress.
However, there are unlimited more adresses with those starting bits. Not with those firstbits though.

Why would people need to trust me?
I didn't offer the address for taking, did I? In fact I was very clear that those firstbits would be taken after the transaction confirmed.
I don't support firstbits use, much less to be used by persons inexperienced with Bitcoin, as it can lead to errors.
The vanity license plate W00T can lead to errors also. Is that two zeros or two letter o's?
Having a FirstBits address is not that important. It's more of a novelty thing as far as I'm concern.
