Bold move. Curious if CL's next step will be to add noarchive tags to prevent google cache content from being crawled.
Anyway, it doesn't seem right for Padmapper to be doing this, but for god's sake, could people browsing the primary source for residential ads please have a way of doing that with a map?! That's really all anyone is asking for here. Sheesh.
Then there's no harm in their putting the tags in.
