Unfortunately, Fellippe, it looks like you are right. I was able to pull down some stuff from Internet Archive but not much.
One of the more curious things about the [abandoned, outdated and now likely malicious qb64 dot net website - don’t go there] site is that some links seem to work if you are referred by another site. So, if for example, you are referred to a [abandoned, outdated and now likely malicious qb64 dot net website - don’t go there] URL by Google, the page loads. But if you try to reload the same page directly at another time it won't load.
Anyone else able to verify this behavior?
If so, we could probably set our HTTP headers to manually refer to Google so it looks like we are coming from Google when we aren't and be able to crawl the pages...
If this is the case, it seems like perhaps the idea is to continue getting traffic from sites like Google but prevent individuals from actually using the site in any normal fashion.
