Having read here that cloaking for some legitimate purpose does not seem to cause any problem with SE, I am thinking of cloaking my sitemap, using SE spider IPlists, to only allow legitimate spiders to crawl it.

This is just a counter measure against scrapers, who appear to use my sitemaps for scraping.

Before I do it I wanted to ask whether anyone can see any problem could be caused by cloaking a sitemap in such a way and do you think this might be helpful in stopping scraper sites, as they do appear to be using my sitemaps in their scripts and it seems like I am offering them my site on a plate by allowing them access to my sitemaps?
