The idea is a simple one, that there be an option to limit the amount someone can quote or use the spoiler in a single post.
As seen here = Got quotes?
^ There should be a limit.
The reason for this is simple... IF it can be abused, it will be abused. And while you could moderate your site, you and your staff cannot be online 24/7 (all the time). Yet it only takes a moment for someone to mass post this everywhere.
So my proposal is that you add an option which the admin can define on how many (how deep) someone can quote or spoiler.
