Only if you consider DoS as the only downside.

As with this analogy:

1. I put out a bowl of (infinite and cost-free) candy, with my name written on each piece so people know where they got the candy.

2. Some other resident, who doesn't have an infinite and cost-free source of candy like I do, comes along and grabs all the candy at periodic intervals.

3. They then scrub my name from all the candy wrappers and replace it with their name.

4. They put out all the candy, pretending it is their candy.

This analogy is much more accurate than either mischaracterisation in this thread:

1. I have no objection to the other resident using me as an unlimited source of candy.

2. I object only to them obfuscating their source of candy, instead misrepresenting the candy as their own!

Because, you see, no one cared when search engines directed candy-hunters to your door. No once cared when search engines presented the candy with your name still on it.

The whole issue, which is unaddressed by your post, is scrubbing the attribution, and then re-attributing the candy.
