Nothing stays hidden for long.
That's very true. This subject is considered taboo everywhere, but several western societies have been
forced to acknowledge that sexual abuse exists, particularly amongst the clergy/churches - that certainly helped bring in out into the open. It encouraged more victims to come forward exposing family members as well. As for executing perpetrators, I doubt that will eradicate them (human nature being what it is). The best way is to educate the public, make children realise it's wrong and that there are people who will listen to their story and do something about it. By educating society, it puts the spotlight on the whole thing - it may not stamp out offenders, but it will lead to increased prosecutions and jail time. Poland has really only recently become a part of the wider world which would have an impact on how far they've come in bringing this crime to the fore - the whole thing is related to the "norms" in a society and if poles still "beat" their children into submission (as per above article)...it doesn't look good for the children who are victims of sexual predators.
