Naw, his sending you didn't compromise your safety.Well, not NEARLY as much as you posting those pictures.You do realize, don't you, that the little orangey-red series of 8 vertical dots printed in a bar-code like pattern on your envelope have your complete address, right down to house or unit number, coded in to them, don't you. That they are used to sort, route, and finally deliver your mail. That they are unique, even having a processing date and time and unique identifier, plus address, encoded into them.I mean, put another way, you've just posted your own address on the internet for all to see.Pretty fucking stupid.PS - I've reported your post and if you're lucky a mod will edit out the links, but those pictures are still going to be out there.
