I don't mean to attack the developers in any way but truth be told, being blocked by more and more websites makes Mullvad increasingly unusable. There are numerous websites that provide 403 and other kinds of error messages. Even on Reddit, I constantly need switch servers to find one that isn't blocked. Not even switching to old Reddit or logging in works anymore in a lot of cases. I can't even watch YouTube via NewPipe and LibreTube without changing servers every few videos now. It's even more annoying when my accounts on some websites get permabanned the second I create them.
It used to be that only streaming services didn't work or that you were fed annoying amounts of captchas, but now Mullvad is being outright blocked by a sizeable portion of the internet.
They seriously need to work out something with IP blacklist creators and/or develop some kind of workaround to bypass these blocks. Even if it is a cat and mouse game, that's still preferable to the current situation.
