Spent most of yesterday looking for keywords which will effectively identify – in order to eliminate – files suspected as containing porn, and especially child-porn. One would innocently assume that it's enough to check the relevant information for appearances of keywords such as "fuck", "sex", "xxx", "cock", "vagina" and several more. I thought, at the beginning, that I can get over it with, say, twenty such keywords.
By the end of the day I had almost a hundred, and the list is still growing. Can't say t'wasn't fun looking for'em, except for one really sad case: "diaper". Don't ask.
Now, having that list, I'm toying with the idea of translating it into Hebrew. Could be useful for some of my future stories.
