Note the "Pounce" setting. WSJT-Z is capable of sitting there quietly listening until the call (or possibly calls?) you want appears, then pouncing on them immediately.
That's actually a handy function, but, like anything else in life, it can be used for good or evil. I've used it when I'm sitting there watching everything but want to make sure I don't miss my turn to call (in essence, I'm still initiating the transmission and I'm at the control point), but I'd never use it unattended. Others very well may.
But in the end it really doesn't matter in the slightest. I guess "
Some People" are content filling up their logs automatically and aren't paper chasers. More power to 'em, I guess. But I maintain that if bots were the rule and not the ultra-rare exception it would be very easy to see who the offenders were.
Fact is, in the grand scheme of things,
nobody cares. If it's illegal (i.e. nobody at the control point), our FCC of 2023 will do precisely...
nothing, and the League doesn't have the manpower or likely the will to actively chase the 'bot operators and disallow their DXCC standings. The rules and regulations are clear, and we, as DXers, can only do our best to follow them as best we can. Set an example of good operating practices, and so on. It's not my concern if you're running full-auto, but if you are I probably won't call you.
But here's the dilema; a nice fat juicy new DXCC entity shows up on 6m, and his operating pattern is suspiciously bot-like. You need that entity, he's loud, nobody's really calling him and you know you could get him in one call. Do you call him? I'll tell you right now, I'd do it in a heartbeat, log him, upload to LoTW and do the ZebraDance™ when it posts as a new one, since I don't know for certain what the other op was doing. Now if he boasts on his QRZ page or in the pages of CQ or QST that that's how he operated, that's a horse of a different kettle of fish.
