Lemmy mainline could also skip rich link preview generation if it returns a non-2xx status. Have a few retries if link preview generation fails, and omit the preview entirely if retries are exhausted. I think the Attention Required! | Cloudflare prompt is associated with a 403 Forbidden status code.

And also generate some logs of what addresses are being refused, so the Lemmy admins can reach out to the content owners and get their servers unblocked, maybe.

It depends on the method of PR you’re using, but if people value “one constituency, one representative” (or “equally distributed Parliamentary power among constituencies”) the idea of having a pool of representatives that aren’t accountable to any specific constituency could be a downside.

Eg. if you use a “closed list party-list proportional representation” where the parties get to pick who gets the ‘proportional seats’ from their own ranks, then some MPs are accountable only to their own parties; they don’t have constituents that can threaten their jobs.

But that’s easily addressed by just using a different kind of PR. RCV-PR uses ranked ballots where voters support individual candidates in a multimember district, and dual member proportional has its own apportionment method that gives every constituency two representatives accountable to the voters of that constituency.

So as far as weaknesses go, that one is an easily mitigated one.

In case the majority is the extremist party, PR allows a sort of damage control.

I’m not sure I follow. If an extremist has an absolute majority, ie. 51% of seats, then they have control?
