ip info really doesn't mean much. for one, no one can trace anything back and know for sure who the user was at whatever time it was used. for another, ip's are static and change and/or shared constantly, which takes us back to the first statement.
now what is bad is posting incriminating evidence backed with pics that can be easily matched...i could go on and on but no time right now. but if you think about it all, including the logistics involved i think you'll see where i'm heading...logistics alone would hinder all but the largest of agencies and if they're on to you there's not much to do but run anyway...know what i mean?
