I haven't had a look at the original text from China, but wondering how much they accounted for. Any of these rules could be easily circumvented if they didn't account for multiple scenarios.
Rewards for spending money within a game for the first time
"We don't have a reward for spending money for the first time, but everyone does have a digital coupon for $5 off of their first $10 purchase when they make an account."
Rewards for buying consecutive microtransactions
"The players don't get any extras when they buy more of our digital currency, but every gacha pull does make the next 5 pulls a bit cheaper."
Rewards for daily log-ins.
"No, we're not giving rewards for daily log-ins, but players can buy this bonus that adds a gift-giving NPC to the main town for 30 days, who will trade a small parcel of premium currency for a single gold coin once per day."
