Some of Minni's confusion is probably because of this line ⬇:
Relatedly, if TV-Tropes has those backed up on the Wayback Machine, would it be acceptable to use those examples? I mean, the examples from the Wayback machine are, for all intents and purposes, were discarded and, by that logic, TV-Tropes can't have too much claim on what the site's admins have chosen to discard from the site.
As for legal issues, someone did say that TVT did get in some legal trouble or, otherwise, consulted with their lawyers about their legal license and so they were made to cool off over it, however, that person's offered no sources to that so take it with a grain of salt.
In short, since those examples on TV-Tropes anymore and since any page archived in the Wayback Machine would (ordinarily) count as "discrarded", would it be okay to use those?
