I imagine there are a few trade-offs when flicking the "post-history" switch either way.

Post history On: You get to follow a users comment history. If you read an insightful comment by them, and want to read more, then having a history is nice. Users are people

Post history partially On: e.g. comments could decay to anon after some period. (Cue the sites that collect all post data and match to users) Slightly increases the cost of doing a deep dive on a users history. Users are people, fading to ideas

Post history Off: Lowered attack surface for people who are actively trying to find an argument with you. Less pressure to have a persona consistent with the typical one of any particular community. Users are ideas
