I mean, it's the Internet Archive, which is probably some huge server farm with petabytes of hard drives. I've started uploading my scans there because it's pretty much guaranteed to be up 24/7. I haven't had any problems with them, but I don't think it's a good idea to limit where you upload your mags because that's like putting all your eggs in one basket. I'm thankful for them because up until now, I've been putting my scans on Nyaa torrents and another site. I don't mind if people reupload my scans, either, as long as credit is at least given. At the end of the day, we're here to share content, right? It's not like anyone here is making money off of it (hopefully).
