How do I report a user for completely ignoring all submission rules?

The tosspot has posted over 38,000 outlines and summaries for shows and films they haven't watched. They don't even get the most basic details right, but invariably watch the end, so they can post spoilers and ruin things for everyone else.

I've deleted a few hundred of these submissions, but, unless you're gonna pay me too, I'm not going through 38,000 contributions that someone who is being paid, approved.

The has to be a more sensible way of removing a particular user's submissions, than going to THIRTY-EIGHT THOUSAND submissions individually, and writing a summary I didn't want to write, to show why they need deleting.

You're supposed to be a trustworthy site, could you at least pretend to care whether you are giving accurate information?
