Hello there with all that i think it's not matter if we like something or not, but only if it's legal to do in SL after gacha ban, as for your concerns, it's just a matter of scripts to write code that prevents those type of people from ruining the fun, they can be banned from using the machine if not buying anything but keeping it locked, as well as there is a timer, you have to buy something or release it, and after that release you wont be able to use it for X time, also every question you have here will be on the vendor, so it will tell you if it will ever change, or when yo expect that, but again, those are not the concers here, how it will work or who will have problems with it, or who will be annoyed by that doesn't matter now. the question is if it's allowed to do
Best regards
