I don't see anything all that strange. If you're going to identify parked domains with automation and do it at massive scale, then you need to code some logic. Calling that routine a "classifier" makes sense to me, especially because they need lots of different website classifications. It also makes sense that from time to time they would find ways to improve that code/logic, which they reported doing in November.
