normal sites, sure we want them listed by as many search engines as possible. but since proxies are sort of on the downlow, is it a good idea to submit them to SEs?
according to me there is no wrong in that. people are submitting all sorts of sites to search engines.
whether proxu site or any other site, you do not need to submit to search engines anymore. submitting to search engine practice died long time ago. you just build backlinks and search engines will find your site thru backlinks
