I have a question. What does the Custom option on the Content Filter means? Specifically on the Whitelist.
The content filter tag list is filled by the individual XML files in the "data" folder of the game. Those are basically presets, so event authors and players are on the same page about what things should be filterable.
However, it's perfectly possible to also add custom tags to images that are not yet represented as XML files in that folder. For example: if a modder had an "armpit" fetish and some of his mod pack contained images with that specific content, then he could tag those images with "armpit" and tell the players that they can disable those images by manually entering "armpit" in the blacklist.
Generally speaking, any tags that can't be associated with an XML file will still show up in the "custom" section, so adding or removing an XML file does not result in any data loss in terms of tags associated with images.
The whitelist is just to override any matches from the blacklist. So if for example you have "bigbreasts" on the blacklist and "armpits" on the custom whitelist, then you would still get to see images that are tagged with "bigbreasts" as long as they are also tagged with "armpits".
The custom tags could also be used by mod authors to make it possible to toggle a mod on/off by using a specific filter tag.
