I don't see the point of that. Perhaps they're trying to increase the weight of the pills mentioned as a global keyword, or bring down the reputation of random LJ/blogs in order to relatively increase the reputation of their splogs.
Most likely it's being done manually, but people unclear on the concept. Rules of Spam #3.
Or maybe they're just trying to let me know they aren't the ones who also like Journey.
I've given up wondering why that entry, and only that entry. I assume it made it into a database somewhere. Doesn't really answer the question, but it's not a group I should expect to be acting logically. Again, see Rule #3.
