To prevent leeching, maybe there could be a rank added which is lower than prime that you have to purchase for way lower than $10, like maybe $2.50 (I'm a poor boi, I cannot make $10 to spend) Which could give you access to some sort of Premium Leak forum or whatnot.
Since the above will probably not be added, another thing you can do is make them have more strict requirements, like they have to have a confirmed email address, one confirmed social media app, and have 2 factor authentication. Then to even be able to access the leaks part of the forum, they should have at least somewhere between 50-100 posts. To top it off, they should also apply for it stating the reason whyand what they can contribute to said forums.
Either of these can either be really beneficial to the forums, or extremely tedious for current members.
I'm personally against both of these suggestions. The forum should be accessible to everyone, and not everyone has money or a payment method, and not everyone has a good means of 2FA. Not to mention that not everyone wants to associate any sort of social media account with Nulled (myself included).
There's nothing too wrong with how we're going about doing things right now. Perhaps, if the userbase grows exponentially larger, it could be changed to accommodatesuch a large amount of people, but as of right now the automated systems we have in place alongside a working staff team and users who report rule violations are in no need of replacement.
