According to his comments, BL is aware of this situation and has apparently been emailing back and forth with Tumblr for several months on the issue, so it's unlikely that this is a response to the recent STGRB brouhaha. Dawid thinks it's more to do with the way BL's links are configured (using shorteners).

Ah ok. Yeah that linking that totally sounds like something programmers will need to deal with.
