This list purposely excludes: A) child pornography, B) markets (which are almost certainly scams), and C) interactive sites with little to no moderation or with a high concentration of unpleasant users. Judgement about what falls under these rules is completely arbitrary and at the webmaster's (my) discretion. You are free to make and maintain your own list with your own rules if you do not agree to this curation.
Being listed on this page does not imply I necessarily endorse any of the ideas these pages may put forth. Proceed at your own risk.
Checking is now (most) every week in order not to disadvantage servers that go down for maintenance at the beginning of each month (which was the original check interval). It is week number .
