Post-account-activation delay-error should tell me about the duration

[thetillhoff]

After creating an account on your site, and activating it, I got the following error message when trying to log in:

Sorry, you cannot log in yet. As an anti-spam measure, there is a delay after activating a local account before you can log in.

I've now waited for over 10 minutes, but the problem persists. It's really annoying to not know how long the delay is. Is it a minute? Five? Ten? Is it 24h? Not knowing the delay means I'm brute-force guessing that delay :( Which in turn creates unnecessary traffic on your side as well...
