Without any unique identifiers all they can do is create a system profile which at best only indicates the possibility of multi-clienting or ownership of multiple accounts but isn't absolute proof of either which is where they would have to look at other account data for more evidence.
Perhaps it's time though for a feature in bots and MCs to spoof this system information to a random or a specified configuration, if nothing else it would get rid of one point of possible evidence against you.
