There is another reason why warnings about speeding is not an accurate comparable: If you are warned about a speed trap on Glenmore, for instance, you will do one of two things: You will either be stupid, speed anyway and still get fined, or you will slow down on that stretch of road. Given the entire point is to slow people down toward the limit, the traps are actually more effective if people know they are there.
Checkstops become less effective if their location is known. I agree that people should not tweet the location of checkstops, but I also agree that you can't reasonably restrict the practice. One thing that might help is if the police invested in a second checkstop unit. Dodging one is easy, dodging two becomes more difficult.
