You can do that, but you may want to review some of it - depending upon your system policy.

Users often have a habit of submitting anything they don't want anymore as spam --- that can include everything from personal emails containing jokes they don't like, to trade subscriptions, to direct advertising or even order confirmations from companies they do business with.

We classify sources that receive user submissions as "usertraps" for precisely this reason and we use different rules for processing the messages we receive there. We will skip these kinds of submissions when we see them, but I wanted to make sure you were aware of it ;-)
