"by hand" means "using an automated tool" in snark, of which I am fluent. At least it should be. Our records show that the user was throttled several times. This only happens if the user isn't looking at what they are doing, which generally means it is a bot. Regardless, read the message and slow down.
Give me a break... I've had the same problem as lots of GC.com users the past couple of days, but tonight was by far the worst (so from my perspective, the problem isn't getting better). I'm using a laptop and a keyboard and my own brain. Yes, I type 130 words a minute, and maybe GC.com can't handle that. I'm using IE and am not using any automated tool to browse caches. I was doing what I've done hundreds of times before: simply using Google maps to search for caches, and got locked out for 12 minutes and 45 seconds. It's been interesting, reading the complete forum thread on this topic, and seeing how many Premium members like myself have been throttled to the point of not being able to plan the next caching trip, or log their finds. It's a pain in the... well, you know. Hope you can find a solution soon.
