Immediately lost my "Trust".
Added to that, knowing how persuasive and creepily mad London politics is about evading privacy is (even more than the US), this being a blatant double agent maneuver, wouldn't even surprise me. Maybe some now suspect journalist, who thinks, he needs to hide traces would jump into the trap. So this would reduce the IP's to those people, who feel like they need to hide something. Everybody else already knows that this info can be easily found out by sending an email to yourself. It's obvious that gmail doesn't need your IP, they have your social profile and all you web-habits recorded actively (services) and passively (adsense)
In the other case that this is legitimate company not serving as a shell company, not trying to collect IP's or E-Mail addresses. I'm sorry for spreading paranoia, to those who are sensible about it.
