A #VPN provider that I used shut down without much notice (in fact, the only way I found out was that I visited their site months later, trying to figure out why I hadn't been able to connect).
The #hotel I was using had a local provider that blocked #Fediverse instances (including Mastodon.Social), #Diaspora, #XMPP, #IRC, and a certain mail provider that I still use. They did not block: #Facebook, #Twitter, #GMail, or Outlook / #Hotmail
Because I couldn't connect to the VPN, I discovered how many perfectly normal sites were blocked because they weren't on the top 100 list. I went downstairs and informed the front desk that I would be leaving their establishment because of their blocking.
I received a phone call from their networking vendor, who logged into their router and proxy and turned off filtering on a list of about 25 sites they'd blocked.
But the point is, the hotel and its provider cannot be trusted not to fsck with your data. Always use a VPN.
@Gargron I never understood underscore filtering either (but that's not the issue in this thread). But then again #Gmail ignores (at least) dots in their usernames, so there's obviously some sort of use to it (less confusion for example: a_____b vs a____b <- who is who?).
Every time a #GMail user is unable to receive my #email because #Google inexplicably ate it, and someone suggests I should give up on !selfhost'ing and just let Google manage *my* mail too, I can only think "are you insane!? Then *I* wouldn't be able to receive e-mail either! Why would I want that!?".
Once I tried to help someone setup #gmail to handle their e-mail. It was confusing and I could never make it work, so I just !selfhost'ed instead. Works better.
