How to forbid quotes modification ?

Hello :
On a phpBB forum, somebody quoted my message in an answer, modified my quoted text and included a malicious link. The moderators did not notice it, not checking the text in the quote since it was supposed to be mine.
Is there a way in PunBB to forbid modification of a quote or to forbid any quote (I mean any text styled as a quote) ? Or at least to delete links in a quote ?
Thanks
