If you assume every problem is caused by actively malicious intelligent agents, then there are no complete solutions (or very, very few). Luckily the combination of actively malicious and intelligent isn't so common, so you can get away with making the problem just slightly harder than people are willing to deal with to get whatever kicks they get.
Given the lack of of any evidence, I assert that most of the percentage of people who a) notice a problem, b) care, c) know how to fix it; probably deserve to be using the resources anyway. Besides anyone who doesn't deserve but still fixes the problem will likely be able to, and want to, circumvent other measures.
