"Singles spam at top of ramp at 123rd South/I-15."
An IMAT Solutions spam is at the top of the ramp by the left-side ramp metering stoplight, going south into the freeway.
It's a small one, easy to miss, but it's right in front of the stoplight pole. The pole and ramp metering lights are just before the ramp merges into the freeway.
Keep this interchange patrolled as frequently as you can, spammers have found this to be an easy place to put them. Better yet, keep all of the I-15 'SPUI' interchanges patrolled, they have all seen some sort of spamlately.
