Recently active topics in twitterfeed tagged with retweet

A twitter account with the name 'haikutwaiku' has been causing some serious repetition, by using twitterfeed to retweet posts via an RSS feed of the search results from summize.com that contain the word 'haiku'. The problem is that the word 'haiku' is contained in all the retweets, and thus it is retweeted and re-retweeted and so on. I've definitely seen sixfold repeats, not sure if there have been more.

My first thought was just that it's really annoying:
1. The hashtags.org tracking of the #haiku tag has its numbers skewed, and now its popularity is artificially enhanced
2. It's difficult to find the original source of haikus, and the retweets lack the context of the source ("who said it" is at least as important as what's said!!)
3. The haikutwaiku account itself isn't even useful for tracking haiku, because it's loaded with so much repetition.

I do have a workaround for #2: Instead of doing a summize.com search for haiku, I simply search for haiku -haikutwaiku, to eliminate all posts containing that userid. But this doesn't help "fix" the problem, not really. And even worse: all this repetition could be abused to put undue strain on all parties involved (and as we've seen lately, twitter does not need any more strain!)

I reported this to twitter, and so far they've just said that the user isn't going against any terms of service so they can't reprimand the account. But they are looking into doing something. But what? and when?

Not knowing that, I'm turning to twitterfeed, hoping there's something on your end that could fix the problem. Actually, as I'm typing this, an idea is forming... perhaps a simple fix would be to filter out RSS feed items that contain the twitter userid that twitterfeed is feeding. Then pretty much ALL "infinite-loop" situations would be avoided!

This might bother people using twitterfeed to feed from their blog to twitter, if they have a twitter userid that is a common word or name used in the blog entry titles. But would the reduction in spam and overhead be more than worth it? DISCUSS! :)
