- Scraping, when my scraper gets blocked from the real estate site, wallpaper site, etc, I click next IP, change my UA and I'm ready to go for another round. You can play cat and mouse all day without worrying about all your IPs getting banned.
- Avoiding DDoS attacks, if you're doing something that makes you likely to become the victim of a DDoS attack, like say, joining a script kiddie's botnet IRC server, not giving a crap if your public IP gets dropped is pretty handy.
- GeoIP bypasses, allows you to work around everything from region locked content to discriminatory pricing
- Country-wide and default blockades, many countries censor the internet only in minor and weak ways, blocking things like BitTorrent tracker websites by domain or IP that commercial VPNs will trivially bypass
Are they? So far every leak I’ve read of, has been by pretty shady companies. This seems more like evidence that if you buy a pacemaker from aliexpress (or in the case of NordVPN from Wirecard or Theranos), you might die from it failing.
EDIT: To clarify, I know my ISP's spying on me. Therefore, in some models, trading that against a VPN service that might be spying on me in the same way could be a favorable trade. YMMV.
However, it's a misconception that VPNs provide privacy for browsing the public internet. As we see, there are many weakness.
If your crime is downloading Frozen, and the authorities can’t find any trace of the movie on the device the logs claim was used, then it would be shameful if the logs alone were enough to convict the person.
If you have a server, allocated an IP, and someone sees that IP... that's a pretty direct tie.
Not if you pay with cash (such as Mullvad). Then it depends on what they can infer from your traffic.
