+ * Currently here goes:
+ *  - Leetspeak (using numbers instead of letters): l33t spe4k
+ *  - Crossing fields (moving a part into the next field): ["Danie", "lJohnson"]
+ *    This often happens unintentionally.
+ *  - Writing out numbers where digits are expected, for example in house numbers.
+ *    For example "twentyseven" instead of "27".
+ *  - Using visually identical or similar letters with different Unicode values.
+ *    Mixing scripts: For example mixing the Cyrillic with the Latin alphabet. Cyrillic has visually identical letters.
+ *    Same script: For example using the lower case L for an upper case i (l vs I) and vice versa, using a zero 0 for an oh O.

+ * Classification of risks.

+ * <p>In some situations the exact classification is difficult.
+ * For example a person's name may be from fiction, but also be famous at the same time.</p>
+ *
+ *
+ * Possible values are are listed here.
+ *
+ *
+ * RANDOM_TYPING
+ * This kind of input is often used to quickly pass mandatory fields in a form.
+ * Example: "asdf asdf".
+ *
+ *
+ * PLACEHOLDER
+ * Examples:
+ * For person name: "John Doe".
+ * For person title: Example: "King Peter"
+ *            The given name field doesn't contain a given name, but has at least a title.
+ *            It may, in addition, contain a salutation.
+ * For salutation: Example: "Mr. Smith" (Mr. in the given name field).
+ *                 The given name field doesn't contain a given name, but has a salutation.
+ *                 There is no title in it, otherwise PLACEHOLDER_TITLE would be used.
+ * For place name: "Anytown"
+ *
+ *
+ * FICTIONAL
+ * Examples:
+ * For natural person: "James Bond".
+ * For legal person: ACME (American Company Making Everything)
+ * For place: "Atlantis", "Entenhausen"
+ *
+ *
+ * FAMOUS
+ * Examples:
+ * For natural person: "Barak Obama".
+ *
+ *
+ * HUMOROUS
+ * For natural person: "Sandy Beach".
+ * Place example: "Timbuckthree"
+ *
+ *
+ * INVALID
+ * This includes multiple types of invalid form input.
+ * Refusing input:
+ * Example: "None of your business"
+ * Placeholder nouns: "Someone", "Somebody else", "Somewhere", "Nowhere"
+ * Repeating the form fields:
+ * Example for person name: "firstname lastname"
+ * Examples for street: "Street"
+ * Vulgar language, swearing
+ * Examples: "fuck off"
+ *
+ *
+ * STRING_SIMILARITY
+ * The given name and surname field are equal or almost equal, or match a certain pattern.
+ * Example: "John" / "John"
+ * The risk score is culture adjusted. In some cultures such names do exist, however, a risk is still raised.
+ *
+ *
+ * OTHER
+ * Everything that does not fit into any of the other categories.
