What is overlooked here is that those emails are mass generated spam promoting useless sites. The "how to" tips are irrelevant for the sites being promoted- that's why they are promoted in the manner LW objects to. Web publishers with useful sites generally do not follow the spam script.
The problem is not what's in the email. The problem is the useless sites being promoted. Trying to get spammers to write better emails is pointless. You're just going to end up with better emails promoting the same useless sites. What is the benefit in that?
