Cannot allow anons to post/score comments

[ioistired]

when trying to leave a comment as an anon, i get an error like this:

sqlalchemy.exc.IntegrityError: (psycopg2.errors.NotNullViolation) null value in column "name" of relation "user" violates not-null constraint
DETAIL:  Failing row contains (8, null, null, null, null, anonymous, null, null, gravatar, 1, 0).

I'm trying to allow anons to make/score comments and edit their own comments. If this is not intended to be allowed, then the booru should fail to validate the config on startup and crash. Editing own comments can be implemented using session cookies.

Hmm I guess the intended behavior is to not allow anonymous users to comment and up/down-vote.

I personally wouldn't be against such a functionality, but how should an anonymous user be able to edit their own comments? An anonymous user per definition doesn't have any identifiers, so should they just be able to edit ALL anonymous comments? You could track user's by some identifier (ip, session-id, idk) but then they're not really anonymous anymore. I don't actually know how other sites solve this problem, so I'm just spewing some ideas.

Alternatively you could allow users to 'hide their name' when commenting, but that the actual comment is still associated with their account (just hidden).

I like that idea but it's separate.

Session ID is what I'm thinking of. They're not really anonymous anymore to the server but at least they're not pseudonymous (having an account) and they'll be fully anonymous again once their cookies are cleared.
