The very long comment cause further problems with the site!
I know there is the option to limit the overall length of a comment!

But when there are many quotes the last user can not add great thing! To solve this problem is he can add an option to limit the number of quotes per comment?
Or even better add a boundary length of each quote? (eg 400 chars per quote)

It's really a major worry to see your site no longer works because a very long comment!

Thanks!
