Users of chaos.social, please chime in:

We try our best not to log IP addresses to give you all the privacy we can. Mastodon, as a software, logs IP addresses in two ways: It saves the last IP address you used, and the IP address associated with each active session (you can review those here: https://chaos.social/auth/edit)

We can delete those IP addresses manually in both of these places, but this would reduce your ability to see where your active sessions come from. Opinions, preferences, thougths?
