[Dshield] Re Dshields email invite: DShield Time Check

A valiant attempt but implementation appears somewhat flawed?

1. Email I received was flagged by RBL listing from Spambag - thus time wasted checking email headers (themselves somewhat obfuscated/suspicious anyway? ** - see below) and then googling to establish authenticity of email. 

2. My ISP uses a transparent cache (interception) server. Dissappointingly this DSHIELD page (unlike a number of other sites) appears unable to circumvent/accommodate this to ascertain true IP? Thus currently for example this process won't work for NTL (UK ISP) users that have Transparent servers enabled in their region anyway.

3. Arguably a tenuous criticism but displaying the sender IP with a request to ensure user avoids reporting it AFTER the TCP packet has been allegedly sent is a tad silly surely?
