They very clearly don’t care about such matter. Or, more accurately, they specifically want to harm people who have committed the great sin of accidentally posting something. Opinions and practices are very different across different projects in the space. Wikipedia and WP commons, for example, have detailed policies for personal data. Commons is so careful about copyright, it sometimes can’t host a file that lots of commercial publishers freely use, such as (photos of) ads or logos that lack explicit licenses. Both approaches have their pros and cons. I can’t help but think both projects would be improved by moving a bit into the direction of the other.
