Member leaking out resources

I just found out one of the members here are leaking out all of our resources (I have his nickname), especially presets and reselling them on their website. That’s gross and unacceptable to me as they’re not even sharing them out of goodwill but trying to monitizing our resources instead.
Just want to check if it’s against the rules here? I just reported to one of the staff members but just want to double confirm.

Thanks.
