Can't you exclude them from a re-lottery if you just exclude all IDs with ID number > 15xxx that have lottery tickets between 23k to 27k or something, I bet you have the better insights to the numbers. Of course one or two legit users will also be excluded that way, but well.
My number begins 15xxxxx and I deposit to make up my entries.
Past few weeks I've 23-25k, 5-6k and 50-55k.
Does that mean I should be excluded?
