Unfortunately we know that some TGP owners sell the email addresses of submitters. So if a submitter wants to protect themselves against that then I think it's OK but they have a better option.
After many years of being shit Spam arrest finally has the ability to allow white lists on a domain level. Basically before the surfer submits to Shemp then they should white list shemp.com so any email coming from him, his reviewers, his scripts and so forth will be automatically approved. Making Shemp do that work is WRONG when the submitter can do it.
Of course if Shemp sends an email from some other domain then that's a different issue but if the email comes from shemp.com then they should be blacklisted for being too lazy to use their spam product properly
Tommy, remember that the submitter is forcing you to so the work that they should be doing
