For cyber police, there are two modus operandi:
1) You set up a trap (say, compromise a CP link or pretend to be a child to meet up with your groomer).
2) You act on the reports of a website.
Since resources are quite scarce, this is how they have to operate around the world.
Of course, since 4chan is an American website, they have no obligation to report holocaust revisionism or whatnot to the German police.
Of course, if you tried this on Facebook, the site might pick up on it due to their moralfaggotry or a policeman or policewoman might unluckily stumble on your post and attempt action on their own.
