I also doubt their lottery system, though I am not sure. But also I think it is not 100% scam. I heard from many known persons that they won. But personally haven't experienced it, so cannot judge it fully.
Many people are in doubt about the fairness of the lottery.
... if someone can figure out a way to implement a provably fair lottery with a variable number of tickets given out each round, I would be happy to implement it. So far I haven't been able to figure out how to do it myself.
Maybe you should use some third-party intermediary for generating random user IDs for the lottery? For example, there is "Audited Lotteries and Sweepstakes" option in random.org.
https://www.random.org/guides/draws/That would not help make the lottery more fair as I can always insert user id's of accounts created by me to the list. Also, that option does not allow for a user having multiple tickets. Thirdly, I have to trust that random.org will generate the numbers fairly and not manipulate the results.
Also, as far as I can see, the results will not be public and people will need access to the random.org account to verify the winning numbers.
