One of the most frustrating things about the tagging system of this site is that I'm the opposite; I vastly prefer moral corruption (of the "character becomes evil" variety). That was the original meaning of "corruption" elsewhere on the internet, and it's been relatively recently that the other definition has occurred (ironically, a corruption itself).
The issue comes from how those two things are *vastly different* kinks, which leads to a nightmare for both sides to try to find games that fit their fetishes. It'd be much better if a new tag was created for one group to use that is separate.
That's not to say I want to take a strong stand that "corruption should only be used for morals/characters becoming evil/changing personality", but rather just that a different tag be used for sexual vs. moral corruption. It's hard to find content that fits my kink now that the definition has been muddled.
