SO, that's annoying and pretty pointless. I can't search the HSDir names or the related content per page. I have to manually and visually look at a map. I was curious if my services were on there, as I run quite a few HSDirs. But no way I'm going to look at every image.
This would have been interesting if they either released the data or make the content searchable. Oh well.
Any bridge can see announced HSDirs communicating to it. So technically you can be a bridge and save all HSDirs that are being passed.
This will get your bridges banned by Tor IF they know you're doing that. So the ones who do, stay quiet about it. I'd give it 3 days before their bridge is distrusted and revoked.
