Automatic deletion of full-quotes

I recently added a post in a multi-post thread in which I quoted a previous post to clarify what specifically I am responding to.
The citation was inevitably made as a full quote, because the cited article only comprised 4 words and could not be shortened meaningfully.

Unfortunately, my quote was automatically removed by the forum software due to full quota.
Perhaps there is a possibility in the forum software to handle this automatic a little more pragmatically?

Not sure why this would be needed then. The post you've replied to is traceable from your reply and anyone interested in what you've replied to can read the original (which is, in this case, the same as the full quote).
