My recommendation is to allow it so long as it meets your criteria.
I like to keep people using either POB front-end for the WOTW contest, but I won't DQ someone for it because I would like to see it grow. However, if that article doesn't meet the criteria I won't curate it. I'll send a gentle reminder to the author of the expectation if they desire additional curation rewards. I can't stop other people from curating it though.
