I swear that two of my HITS abandoned without me doing anything. Two of them were Crowdsource. A message popped up saying I could no longer do any more of those HITS to try others, so I clicked out of it. It wasn't obvious to me that I should return it even though the message said I could not complete anyway. My other issue on other HITS is accidentally pressing the back button or some other button that is taking me back which is causing abandon. I guess I'm not really looking for advice. It's more of a gripe. You'd think they make it so that the system isn't so sensitive to inadvertent abandons.
There's a bit of a learning curve turking. When you run into a glitch like that (specifically the second incident you described), go to the "HITs assigned to you" area and either resume or return the HIT. And do it, like, the second you realize there's a problem.
Don't feel bad, when I first started I had the exact same problem, which made my numbers look like this HITs Accepted 38091 — ... Submitted 36124 94.8% ... Returned 1751 4.6% ... Abandoned 216 0.6% 212 of those abandoned all came from when I first started, and did some HIT's that would do what you said, or by me accidentally hitting back or something like that. Once I discovered the assigned to you page, I only have gotten 4 since. Those were just from me being forgetful though. Doesn't effect you whatsoever. Well, I shouldn't say that, there is one requester (and only one) that I have personally seen that has a certain requirement for submiited percentage. Not even really sure why...that number doesn't reflect the worker at all.
"HITs assigned to you" is a tool for your toolbox. Use it. For example, there are two HITs (or more) that you want to work, but, because we're humans, can only do one at a time. Accept them, do the one with the shortest time allocated first, then go to "HITs assigned to you" and finish the other HIT(s). Don't ever accept more than you can reasonably do because those HITs will abandon if you don't finish the task. ETA: You can have up to 25 HITs assigned.
