Neither. The question here is, are your keys obtained illegally? It coul be safe for you but not for your customers.
Anyway, I think it's best to use bitcointalk escrow so tey can first check if the keys will work or not. I don't know if bitify checks it so just use escrows in here. See this list for reputable escrows: https://bitcointalksearch.org/topic/bitcointalk-escrows-trade-safely-855778
