A recent user has been posting a lot of questions recently, none of which add much value to our site. They are all part identification questions, and the user has not shown any initiative on their part to do any research. It feels like we are his free employees to figure out what LEGO sets he has acquired.
Besides downvoting his questions, what other options do we have to either force this user to do more effort (and hence post less) or prevent them from posting similar question barrages in the future?
