Hosting providers are theoretically in a key position to combat cybercrime as they are often the entities renting out the resources that end up being abused by miscreants.

Present bias—a tendency to give in to short-term temptations at the expense of long-term outcomes—is a potential driver of low adherence. In this study we test a nov...
