spam protection

Hi,

I would be really grateful if a simple spam protection could be added. I have tribune on a busy website and we often get the immature spammer that would send like 20 messages in a row.

I'm thinking 2 types of spam protection:

1. Use some kind of delay before new post can be made. Like 1 message for the user every 10 seconds maximum (value can be adjusted in a setting variable)

2. Limit user to say 3 messages in a row until someone else reply... again number of consecutive messages by user adjustable in setting variable.

I would say anyone of those 2 suggestions above would make my life much much easier.

btw I am happily using the nodejs integration module with tribune and very happy with it... would it be hard to accomodate the spam protection for the nodejs part as well.. that would be great.

Cheers and thanks for the hard work!
