I’ve attended a seminar for child protection before that was delivered by a former cop (that worked in the sex crimes division) and they said the exact same thing - in the context of correctly making the distinction between paedophile and sex offender.

I would have used Owncloud Infinite Scale but the fact you can’t use your own existing files makes it a complete non-starter for me. I don’t want my files locked behind Decomposed FS.
Unless I’ve read things wrong, which is entirely possible.
