    Once mod_mam is loaded, it will log data for all users on the server, even for high-traffic users who never actually use MAM. Please copy the behavior of ejabberd where MAM is only enabled for a given account once that user accesses the MAM archive once.

    Unlikely to happen in 0.10, however it could probably me made as a plugin.

    Just to reiterate that this is also a data privacy problem. MAM is auto-enabled for users without any opt-in. A MAM-enabled client at least in theory could inform the user about activating server-side storage.

    And to document the admin console "workaround", which I ended up looking for in the prosody MUC logs multiple times now, which disables archive for individual users: >require"core.storagemanager".open("SERVER", "archive_prefs", "map"):set("USER", false, false)

    Convinced by ge0rg that a user without a MAM client has no way to opt-out, a user with a MAM client may.

    Should this go in 0.10 or trunk?

    Please add it to 0.10; I'd be okay with it being off-by-default to not break compatibility. Probably this setting mostly matters for public servers only anyway (due to privacy laws), but I don't want you to make it depend on whether IBR is enabled.

    Done in https://hg.prosody.im/0.10/rev/3eb4cafb3b64
