Matthew 10:14 "And if anyone will not receive you or listen to your words, shake off the dust from your feet when you leave that house or town."
Jesus is speaking here to his disciples as he sends them out help the lost souls of Israel. He very clearly commands them to get the hell out of there and leave people alone if they are not accepting of his message.
You have delivered your message as Jesus required. Everyone on the blockchain has received it. Now leave them alone - if they want more, they'll seek you out. Otherwise, you are directly disobeying Jesus.
