Bluemist noticed Direct-Anime, went into a tl;dr mode. I am ready to fight with scrappers, but so far there wasn't a cause. Direct-Anime pulls from Antenna, not from me, so the decision to poison their feed and/or block them rests with my provider, because all AB blogs are aggregated by Antenna.

UPDATE: Maestro pointed out that I was wrong: Direct-Anime scraps directly from AB subdomains, and a quick look at logs shows that it is indeed the case. This revelation, I suppose, puts the ball in my court for careful application of .htaccess.

UPDATE: Maestro went ahead and changed my .htaccess before I got around to it. I wish I could say all is well that ends well, but it did not end well nor did it end at all. Firstly, Maestro took this entry as belittling AB and became unhappy, which was not a good thing. Secondly, scrappers never give up and I am yet to figure how to make WP feeds to be salted with the requestor's IP.
