Your attempts to exploit it yourself, plus this message, have now brought it to our attention. We will work on implementing a fix, either by putting in validation to prevent dust orders that would result in this rounding issue, or by increasing the minimum allowed order size.
I don't know what "various channels" you used to try to report this issue. We know of no attempts to do so. Simply reaching out to Aggroed or one of our active developers directly on Discord would have been a more constructive way of getting our attention than the approach you have evidently taken.
