If you're going to attempt stealth spam, you really GOT to learn not to spam the same couple of newsgroups serially with the same message. It makes you not merely look like a crooked cheating lying scoundral, which stealth spammers inherently are, but it additionally makes you look insane for having thought it might pass undetected & actually generate sales rather than the ill will your sort of crookedness requires.
Everyone who deplores spammers & deplores lying crooked stealth spammers even more should report "Russ" & summerseat.com at minimum to: snipped-for-privacy@google.com snipped-for-privacy@yahoo.com be sure to send all the headers when reporting crooked spammers.
And of course it goes without saying, NEVER buy anything from summerseat.com. Spammers crooked enough to attempt stealth spammers are apt to be crooked in every other aspect of their dealings. The fact that the site sells for an inflated price the type of low-end lawn furniture you can get dirt-cheap from a local vendor in any town shouldn't make it hard to overlook such a cretinish company as summerseat.

When discovering someone crooked enough for stealth spam, expect that they could be capable of ANY criminality.

Their endeavors are crimes & they are responsible for diminishing freedoms on the web (because as more & more governments criminalize their behavior, other restrictive legislation tends to tag along & impacts authentic free speech). Their behavior imposes all sorts of hidden costs on all of us. Here's a great page on how to fight these sunzabitches:
