I agree that Lottery officials do monitor this site, however I don’t think they care about your system until it starts costing them money. That is, you start WINNING!
For example, I discovered a pattern in the Virginia Pick3 game that, when back tested, was profitable for the past two years. I exploited this pattern for a few months in 2014 winning 2 to 3 times a week on $18 bets (2 bets per day). Then suddenly the pattern failed for two weeks in a row, so I decided to cease playing until I saw the pattern resume. It did not.
Below is a link to a chart of the profits, and losses, from this pattern (I stopped using it two weeks after the peak profit). Sure looks like something changed to me.

I think my mistake was always playing at the same lottery retailer. It likely threw up alarms when someone kept winning at the same place at a high rate. Also, note the Virginia Lottery uses Machines and Balls. If you are interested, the pattern I found was a set of 18 numbers, they were:
051 108
135 255
278 358
381 465
490 493
607 614
631 671
710 815
871 992
