it may become more trivial to llm your comments/blog/whatever into a different "voice", but there is so much that can be used for de-anonymization that the llm-assisted technique dont address.

for example, you may change the content of your comments, but if you only ever comment on the same topic, the topic itself is a signal. when you post (both day and time), frequency of posts, topics of interest, usernames (e.g. themes or patterns), and much more.
