EDIT: so, apart from posting the address across as many channels as possible, and telling people to cross-check, what options are there? You could announce addresses way beforehand and have them send ETH to the final address once you release it, using that as a signal.
Usually, companies conducting ICO's only release the block number in advance, the smart contract address is generally released last sometimes just hours before the ICO start time.
