Brute forcing all lower cases in l?l?l?l?l?l?l?1 x 1000 to look for name patterns might be not the best idea. A smarter way is to substitute each | in a single mode and each group of subsequent | characters in length mode by a name from a chosen country. Doing so will dramatically decrease the search space.
single mode: 12|1992 --> 12jan1992 12alex1992 12simon1992 12martina1992 12michael1992 ...
length mode: 12||||1992 --> 12alex1992 12lena1992 12lora1992 12vika1992 12sofi1992 ...
