Ask HN: Open Source Regulatory Compliance Dictionaries / Word Lists?

The email gateway market doesn't appear to have any FOSS regulatory compliance software available to those who may need such services on a budget. It got me thinking, that a Wiki-like repository of reg. comp. word lists might help facilitate development of such a thing. Does anyone know of whether such a thing already exists? Might this be a good project to start? These word lists are incredibly long, but I would imagine they could be group curated in a relatively short period of time. I could never do it alone, but I might be able to set up a Wiki for that purpose. Thoughts?
