since privacy issues were a topic addressed in the paper, i assume the data were anonymized before the analysis (for example by assigning a random number to each account and stripping the identity information). However as I understand it, basically all our games are accessible to anyone in a publically accessible database. Its up to you to protect your identity on your lichess account.
An interesting implication is that one could create AIs playing in the style of anyone who's game you have and access to and 'impersonate them'. Also one could link public and private accounts (which are allowed by the TOS under some circumstances). This would allow private accounts of super GMs to be revealed.
