I'm not entirely sure how this works?
I have an image that sold twice on the same day, so surely after the first sale it should have been bumped up into the next level?
It started as level 1 (newer than 6 months, no sales)
after the first sale shouldn't it move into Level 2 (orange) of 1-4 sales?

i have another image that sold in this order:
level 0 older than 6 months no sales, even though it was <one month old when it sold.
then moved to level 1.
then to level 2.
then back to level 1.

it's bad enough that half of my sales are sold using 2010 subscriptions (people hold credits for 2 years? and not just a handful, half of them?) but I'm finding this levels system hard to understand.

It appears that some of my images have been messed with - do they have some kind of auto keyword fixer device that is causing more harm than good?

An image of mine, smoked salmon with poached eggs on sourdough toast contains neither salmon nor eggs in the keywords. Fairly sure i would have thought to include those (yes, i checked in Bridge, my list of keywords is long, and the list in iStock was slashed down to about 9 terms). 

Next question: will it just keep happening automatically?

about 3 hours ago i tried to log in, and went through  about 10 log in screen with my security code (the one with the blurry words) being rejected.
Gave up and came back now. Have repeated the same actions at least a dozen times.
Frankly, I reckon a computer robot could beat their stupid blurry coded words quiz better than a human!!
