For about 12 hours, I've been getting hit heavily by texas-holdem spam. This, coming just two days after "texas-holdem.rohkalby.net" "spam-whacked" (to coin a phrase) its way to a high position in the Daypop Top 40, one of the key indicators of memetic activity in the blogosphere. It didn't stay there more than a day, but it was there long enough for my 12-hour aggregation cycle on Daypop Top 40 to pick it up.
This wave of comment spam here (all caught by my filter, after the initial training) is conventional comment spam. But my hunch is that the "rohkalby.net" Daypop-whack was done with trackback. I just can't imagine it happening rapidly enough and in a widespread enough form to do so without the assistance of trackback auto-discovery.
BTW, I haven't found anybody actually mentioning this incident, which is very interesting to me. It meas, I think, that they either didn't notice, didn't understand the importance, or didn't want to admit the importance. Which is huge, because this would demonstrate two things -- one very important, the other merely interesting:
We can say safely that SixApart are responsible, by the way, because they initially invented trackback as a manual means of "giving juice" to someone else, and then failed to understand that it needed to stay manual. It was intended to be initiated by human action, not automated. But then they proceeded to automate it; that made trackback geometrically more attractive as a target for spam: It meant that spammers could potentially place themselves into the various automatically-compiled "top"-lists in a completely automated fashion (i.e., at cost to the spammer approaching zero). And with no legal consequences, to boot: They couldn't be prosecuted under email laws, because it wasn't email; they couldn't be charged with theft of service or hacking because -- and this is key -- the spamming was being carried out as a normal designed feature of the "exploited" systems, using their resources.
The great mystery isn't that it happened, but that it took so long to happen.
Shelley et al.'s "tagback" concept might profide a "fix" for this, of a very limited sort, but it still leaves us without trackback. Trackback was a very useful concept; it allowed people to create implicit webs of interest, one connection at a time and without central planning, and -- and this is really important -- without the mediation of a third party like Google or Technorati. And we all know that spammers will find a way to parasitize themselves onto tagback, as well.
And anyway, reliance on third parties for integration gives them power they should not be allowed to have. It's a bad design principle. Trackback, pre-autodiscovery, was a good simple piece of enabling technology. But it was mis-applied, quickly, with the encouragement of people who should have known better. And now it will be forgotten. Which is really, deeply stupid, when instead it could simply be re-invented without auto-discovery.
