> Also, the meanings of emoji change (see the sexual connotations that many emoji have picked up since their release - those connotations weren't present on day zero), so how do you protect against that? I'm not too worried about it. I think that even if in the future the thumbs up emoji unambiguously meant "I like butts" or something a judge would do exactly the same thing they did in this case and apply common sense. A thumbs up today signals agreement, so it meant the contract was agreed to. In the future, if someone goes to court because they didn't mean to sign the contract they could make the case "I was professing my love of butts!" and a judge would say "Yep, that's what the thumbs up emoji means to most people! The contract is unsigned" The precedent here is that intent matters more than a signature, not that the thumbs up sign is always going to be how contracts are signed.
