It's mostly monthly so that I don't have to support people who have purchased 6+ months ago and I have to treat them equally to people who just bought 10 minutes ago. I don't really mind doing so but lifetime users are cumulative so it's annoying to have to support them all. Most software which is lifetime only has a year of support, with an option to buy additional support time. So the fact that vape 2 provides lifetime support and updates makes it unique in that regard, especially considering how viotile and problematic it can be due to its nature.
Vape lite is also in reality cheaper to most people. The majority of vape users only use it for a couple months then quit cheating or minecraft in general.
and yeah, the fact that lite is monthly doesn't stop any staff from buying it. There are many staff whose entire purpose is to try and find vape. Them and other envious people rushed to buy it to try and detect it right away, but despite their efforts over the past 2 months they still can't.
