Every time a comment is made on any CommentLuv enabled site (over 100,000 at last count) means the ComLuv server has to do the checking, searching, fetching and sending back of a feed for every request. With normal comments from normal people, it handles everything just fine and processes over a million comments a month, making a lot of people feel the luv.
The problem comes when the spammers get running and scraping a whole lot of blogs with old wordpress versions or bot-friendly comment forms with the CommentLuv plugin still installed. When that happens, the Comluv server can get hit a thousand times a minute with requests for a feed on a site that has not got one or has a badly formed file. That literally kills the server!

This is why I’ve had to do a mass clear out of spam blogs created here and put in a new routine to ban any url that results in a feed error 3 times or more. I’ve also put in some checks and other space and bandwidth saving measures and hope this will take care of things for a while. Oh gawd I hope so!
I’ll get some tutorials up soon on how to troubleshoot your feed if you’re getting an error and how to unban your site once you get your feed sorted out but if you’re having troubles right now, submit a support ticket and I’ll see what I can do for you..
