Audit what user has uploaded which events

We're in the process of building a new instance of gancio and are accepting new users. We have not yet encountered this case but we're worried that a registered user continuously creates events that are against the site policies.

Right now as admins we don't know which user created which events, so we wouldn't be able to close the user account.

I understand that this may be a design issue to preserve the privacy of the users, and I support it for anonymous users where there is a moderation step. I'm not so sure for registered users given that it may become a moderation hell for the admins.

As an admin I'd like to have an admin page to see the user events to deduce if it's the spammer. What do you think?
