First of all, since you cannot so far offer any references other than anecdotal ones to refute the fact that PRIA requests are not intended to include any warning letters, or that Administrative actions of that variety are supposed to be disclosed, I'll consider that issue settled.
Next, you are using the phrase "lie to employers" to describe my advice about reporting of Administrative Actions. You can describe it that way if you like, but you are taking it out of context where context means everything.
Let's do another analogy. You are looking at a really nice wristwatch for $2000 in a shop and you really think you'd like to have it, maybe it's a new Breitling and the exact color and model you were thinking about buying the last month or two. You do not want pay full price so you say, "will you take a thousand cash for it?" The clerk says, "wait a minute" and goes to the manager, the manager looks at you from afar and sees you have on some nice clothes, then the clerk comes back and says, "he says he'll take whatever you have on you right now- how much do you have on you?" You know you have two thousand in your wallet but instead you say, "well, I have only eleven hundred on me today". Eleven hundred is much less than what you have, and you just told a bold-faced lie. But it was a fair context for telling a lie, wasn't it? If you dished out all two grand in the name of not telling a lie, you would have been a fool. A nine hundred dollar fool in this case.
Was this any better? I tried to create a more pleasant analogy for you this time. I thought it was pretty good, personally. Again, this analogy does not mean we are all just watch salesmen or anything like that. It makes a point, that's all. We can extend it to applying for a pilot job if you like, but I want to see if you are getting the analogy so far.
