At first glance, I tend to agree. I would consider DNS lookups to be much less intrusive than update requests and would not want to risk being flagged as abusive and have my ddns host disabled.

If you can't, you'll probably be using cached data with a remaining TTL of 0-600 seconds, perhaps more. This means that at least in some cases, you'll update based on old data...
