From my own tests with TOR: The hidden services architecture of TOR (i.e. services which only exist within TOR) works more or less like the Internet, so to get to an onion page you have two options: - You use the onion url of a page: You will probably not encounter anything you do not want to see (depending on the source of the link). - You use one of the hidden service search engines. These are NOT provided by TOR but by TOR users, i.e. they are TORs Google/Yahoo (especially old time yahoo with long lists of pages instead of a search). Here the risk is significantly higher: Most of these link lists/search engines have a strict "no censoring" policy, so you will at least risk to get links to such things. I've never had this problem (and I am grateful for that) but the risk exists.
