I tag X engineering about their ridiculous "spam" tags. Either their spam filter really means "stuff we don't like" -- in which case whatever i can't decide that for them -- or it's really broken. It's so new and Twitter having any kind of feature is so new, that I don't know what to think yet.

I had not considered that maybe users were tagging those posts as spam, but I kind of doubt it because those posts have very few views for somebody to have tagged them as spam.
