Several days this month I've received credit for more than one ds when I'm positive I only completed one the day before. Like yesterday, I was kicked out of several in the morning, not making it past the initial questioning, then later in day I clicked "none of the above" and got a random survey that finished successfully. Now today, once again I received two credits and I have no idea why. Because of this, I now have more completed surveys credited than there are days in the month. I feel guilty because I try hard to always follow the rules and wouldn't want to ever cause a problem, especially when some have trouble getting only a few surveys in a month. I'm home alone during the day so it's easier for me to keep trying when I'm booted, but I'm not sure if I should try at all the next 2 days? What do you think?
