No, this affects each and every PieFed instance that upgrades to v1.7 (I sent you in a different reply here the exact lines of code). PugJesus' instance PieFed.social uses the now-default value of 240 as the daily vote quota. Admins may opt-out by setting the quota differently, however this will only impact votes accepted on your current instance. It will not affect votes accepted by other PieFed instances. e.g. if your instance uses 500 rather than 240, then someone looking at the identical content from PieFed.social will not see any of the second half of your daily votes: you will be able to OFFER them, and Lemmy will receive all of them, but each PieFed instance chooses itself how much it will receive or not.

And btw this information is not presented anywhere to show what these values are across each instance. Like the caps on posts and comments, it is silently effective, but not transparent in the least. So like the whole argument about whether defederations destroy the foundational principles of the ActivityPub Protocol-using Threadiverse, this new issue too is going to wreak havoc on the acceptance of PieFed in the wider Threadiverse & Fediverse communities. :-(

Re-creating the comms I run on a different instance.

Most of my activity is in those comms, and there's not a lot in the way of alternatives for most of them, topic-wise.
