Thanks for posting. There is absolutely nothing in any of those links. In case anyone is looking - there is nothing in any links I checked.
A number of those links do seem to have died, though there are still some working.
What I notice is that those that are still working tend to be "pay-for" which suggests a couple of things. One is that only the people charging can afford continue to host, one is that any that were not paying appropriate royalties to the writers have been shut down.
A third is that some were quite old and the people who made them available are no longer willing or able to do that due, perhaps, to advancing years.
