If one is super concerned about their personal security/privacy, they shouldn't be posting messages they don't want others to see on any publicly viewable message board; this is just basic common sense ... isn't it? ... anyways, will add building a board support faq to the to-do list.

With that said, one's message postings (text, pictures, etc) alone most often do NOT constitute anywhere near enough evidence to obtain a conviction, let alone even filing charges in many instances - it most often requires much more ... if one is being investigated, the authorities (often using informants first to troll/establish contact) will seek an in-depth one-on-one dialogue via email, IM, phone, post, in-person, etc over a period of time (can be upwards of years in some instances; months more typical) with the person(s) being investigated.

Finally, in a nutshell, nowhereman hit it right on ... blunt, but right to the point
