Speaking of which, there was a law professor who spoke at that conference on dealing with financial censorship. One of the examples of a term which might be censored with one firm (it's unclear when they did this) was "lolita". This is obviously problematic as:
1) Even the original book was a work of fiction. That was the book which the author wrote something like 70 years ago. The author doesn't seem to have intended anything more.
2) The vast majority of instances of this term seem to involve legitimate content.
