there's NO link as far as I'm aware you just use the same basic idea - apparently Match.Com used to apply autofilters to mails which included external email addresses and wipe out that email and/or wipe out the entire mail. Dave M of Insider Internet Dating found that if you apply a different format to the external email address then it slips through those filters. *** I have read somewhere that Match.com wised up to that trick and it no longer works ***. As I don't use Match I cannot verify this. I certainly know that on AreYouInterested my format works.Why give an external email address? A lot of members of Match apparently are on free memberships and that limits what they can view/reply to...ditto for AreYouInterested.
As an experiment I will try to see if I can pass through the easiest format in AreYouInterested for example normal email
