The change includes the provision which allows law enforcement to:
"...use remote access to search electronic storage media and to seize or copy electronically stored information..."

But this would be enacted without any significant restriction, and crosses international borders without having to deal with treaties, or reciprocal agreements, basically making a mockery of international jurisdictions.  The take on this by the EU will be interesting since their data privacy laws are stronger than the USA protections.

I believe the Feds are doing this to combat ISIS, and other GITMO wannabes!  I would like to think that the guys and the girls who just want to have fun would be far off their radar screen!

P411? I don't know enough about it, and whether all of the information they keep is truly "anonymous." There is always a digital trail.

According to the disclaimer on TER's entry page, this is a fantasy story site.  Any reviews on here are just fictional anecdotes that horny men write about women they salivate over.  You know, like the Penthouse letters.  So one can easily say he wrote a review because he found the provider attractive, created a fantasy in his head, and posted it online.  Will the argument hold up on court?  With a good lawyer, not impossible.  At least less so than agreeing to something on the phone.
