Sounds a lot like email where it is really difficult to self-host your own email server since you'll be flagged as spam. It seemed like something that would happen to Lemmy eventually, but I didn't think it would be a strong possibility this soon.

lemmy.dbzer0.com, instance that has a lot of communities related to piracy and emulation

Or even better, self host so you don't have to deal with admins doing shitty things

Didn't they allow Microsoft telemetry through the tracking protection since they rely on Microsoft for all sorts of stuff despite their "avoid big tech" advertising? There's so many better options, like Librewolf, Mullvad, Orion, Mull, even Brave if you really want a Chromium browser.

There's Orion browser, which is made by the Kagi search people. It is based on Safari, has vertical tabs, has built in ad blocking, and supports Chrome and Firefox extensions so you can install uBO. It doesn't fix the developer issues, but you might like it better than Safari, and it's not Chromium based like Arc browser.

Get Obtainium (downloads directly from sources like Github/Codeberg/etc) or Neo Store (downloads from F-Droid) and you'll get notified about updates.

LibreWolf is so clean and minimal, whenever I go back to Firefox it feels bloated in comparison.

So basically you have the instance you are looking at. That instance has a list of communities (from any instance) that it knows about. A new community is added whenever somebody on that instance views or subscribes to that community for the first time.

When you go to ALL on that instance, it will show only posts from those communities (which are listed in the Communities/ALL tab). So larger instances (which know about more communities) will tend to have more stuff in ALL.

There is also the issue of defederating, where the instance decides to block other instances, and communities from those instances will not show up in ALL.

So ALL is a bit misleading since it doesn't show posts from all communities on the Lemmyverse, but only ones that the instance knows about and chooses to federate with. However, a lot of the large servers will probably be pretty similar content-wise (except for ones like Beehaw that defederated from other large instances for various reasons).

For peers to connect to each other, at least one of the two connecting needs to be port-forwarded, so if everyone were on Mullvad, now no one would be able to reach each other. Right now you can still torrent on Mullvad, but only with (non-Mullvad) users who use port-forwarding.

Mullvad got rid of port-forwarding so it's not good for torrenting anymore. IVPN, which is where the Mullvad refugees fled to, just got rid of it as well. I think AirVPN is the next option people are flocking to, but who knows when they'll do that next.

I've also seen stuff about torrenting over I2P which shouldn't have this limitation, but I'm not sure how usable it is right this moment.

*Get zucked.
