«...told me Bing has “spiders” that search the net and crawl over everything that is said...»
Every search engine does exactly that. I don’t think there’s any other way.
“I was told there is no way to prevent or get your postings off of...”
Search engines must (theoretically) comply with a “no crawling” policy if a server tolds them so. That’s sort of a blurry line, many sites set up “traps” to ban a spider that goes where it shouldn’t. It’s up to the site. If Free Republic doesn’t keep the spider out, then the posting may get archived.
Thanks for the info...:O)
