Comments: Avoid Duplicate Comments

[gene.sis]

After clicking "Send" on a comment, the site would check
if the previously made comment of the same user of the chapter is identical
or
if the time of the previously made comment of the same user of the chapter dates back less than 3 (?) seconds

It should also apply to messages.

I would increase the lead time to 30 seconds, but otherwise second all points.

maybe this could also be done by js. After clicking "Send" it probably could prevent sending further messages from that page until the ajax request returns success or failure.
