I put forum spammers in the same category as hackers. One usually leads to the other too. Its all spam, all of it. If you want to go through life with the "bottom feeder" label, that's fine. Bunch of catfish!
Man, there are some really desperate people out there. Ever see what happens to a site after a surge of inbound links like this? I've seen it a couple of times and it isn't pretty. Any time you are dealing with links in bulk like this, there are spotlights on everywhere.
10,000 backlinks per month? That would be highly unnatural for many sites. That's like putting a sign on your back that reads "kick me".
The only person most likely benefiting from this would be the schmuck selling the scripts.
Added: Ya, I know what some are thinking, "if that were the case, a competitor could wreak havoc on your site." Well, from my perspective, that would be the case if the circumstances were right.
