Prevent posting content repeatedly

[itsrachelfish]

Someone shouldn't be able to post the same message repeatedly, especially not within a short timeframe.

In this thread what spammed the letter 'b' 35 times in a row at a rate of roughly one post every 8 seconds.

There should be speed limits when posting and the same message shouldn't be able to be posted several times.

In order to stop regular posters from getting speed limited, I think the speed limit should increase exponentially.

0 posts in the past minute? No delay
1 post in the past minute? 10 second delay before next post can be made
2 posts in the past minute? 30 second delay before the next post can be made
3 posts in the past minute? 300 second delay before the next post can be made

This way people who are posting once every few minutes wouldn't notice any speed limit, but people trying to spam would.

Posting a single message repeatedly should have the same limits initially but in the final case it should multiply the delay to something like 900 seconds.
