In the olden days, you used to get spam from people running link farms (groups of many-paged sites full of useless “directory” pages with hundreds of links to each other), telling you that they’d added a link to your site from one of their dreadful pages and unless you linked back, they’d DELETE THE LINK OMG.
Back in the mists of time this may actually have worked - if, by “worked”, you mean “artificially inflated the value of these sites so their worthless pollution floated up into people’s search results and they got some ad-viewing traffic”.
It doesn’t work any more, though. Anybody who joins in these scams by linking back now connects themselves to the “bad neighbourhood” mojo that’s applied to all known link farms by the search engines. This achieves the exact opposite of the ranking-boosting traffic bonanza promised by the spammers.
So, nowadays, the spammers have moved on to
trapezoidal triangular linking.
You used to get spam from someone who runs www.creativeusesforsnot.com and is apparently convinced that some random page on your site where the word “snot” appears is a perfect match for his very important directory of links, but not if you don’t link back. Now, you get spam from the same guy, except he’s telling you that if you link to creativeusesforsnot.com, he’ll link to you from elephant-toenail-trimmers.com.
Because the search engines don’t know his two sites are connected, all of these links look like perfectly kosher “one way” propositions, and everybody wins. Eh? Buddy? Buddy buddy buddy?
A few of these e-mails a day have been leaking through to me. Here’s a typically moronic example:

There’s no connection between the three domains mentioned in this e-mail as far as whois records go (although I was amused to note that the registrant of rainforests.com.au put what appears to be his real Australian Business Number in his registration!), but Google would have to be pretty stupid to be unable to connect them. Google are all about seeing patterns in links, and triangular linking creates repetitive patterns. A links to X, then X links to C. A links to Y, then Y links to C. Et cetera. This sort of thing seldom happens for valid reasons.
Oh, and these guys keep sending out these brain-hurtingly stupid e-mails to zillions of recipients, who then post them to the Web and Usenet, where the world can see the scheme exposed. Sometimes the spammers cut out the middleman here, by spamming mailing-list addresses and getting their messages archived online automatically.
So even if these dorks don’t accidentally spam people (or spam-trap addresses…) that actually lead directly to the search engines, they can still be discovered very quickly.
Are they, though?
Well, the root pages for the sites mentioned in the above spam are all still sitting pretty at Google PageRank 4, which is quite good. The sub-pages actually mentioned in the spam are down around PR3, but it’s normal for sub-pages on valid sites to have a slightly lower rank than the root page.
When I looked at some sites promoted in previous spams that’ve been visible online for months - here, for instance - I found that their root pages still had OK PageRanks - well, PR3 at least. More interestingly, the sub-pages that the spam tells people to link inward to are also still doing OK, but the sub-pages that link outward in return are now down on PR0 with the rest of the hoi polloi.
So it does seem that Google is somewhat wise to this scam. If you do what a triangular-link spammer asks you to do, your site’s PageRank mojo will indeed contribute to the PageRank of the page you link to, but as soon as Google notices the pattern, the spammer’s return-link page will plummet to PR0 and so his link will do you no good.
This isn’t an optimal solution, since it means the triangular-link scam will still work just fine for the spammer, if people do what he says. It’d be better if triangular link beneficiaries were being classed as “bad neighbourhoods” just like the old-style link farms.
But if it becomes common knowledge that these schemes are as fishy as they sound, at least fewer people will fall for them.
