I don't know whether the anti-spam product is genuine, though I doubt it - since it's being marketed by the spammers themselves, to what end I don't know.
It started off with "You DON'T want to remove your email address, let me tell you why...", and then went on to list all the reasons why you shouldn't ''remove'' yourself..
Anyone seen this kind of behaviour before?
Yes. It's not very new.. basically the motivation is that many of these fake antispam products are actually email-address-harvesting systems that feed spam databases. Instead of reducing spam, they increase it.
