We generally don't block IP addresses unless we get an excessive amount of spam (or other abuse) from that IP address. So I suspect it's a local problem.

Network admins saw traffic to forums.freebsd.org - thought "what the hell is freebsd", opened the link - saw horns and went "some satanistic forum, can't have that" and blocked it?

Might possibly be a simple, plain network config issue.

Sharing output of terminal commands:

Please use the [code] bbcodes to paste output. Besides making it look nicer it also stops the forum software from mangling hostnames it thinks might be URLs.

I don't comment on that "horn" nonsense, but he has a point. I bet it's a DNS issue (unintentional) in ISP side.
Connect through another ISP and/or carrier, or use VPN and try again. It's better to test it in "Incognito" mode.

[Edit]: Strike-through the DNS work.

I doubt it's a DNS issue. forums.freebsd.org is correctly resolved to 204.109.59.195. So DNS doesn't seem to be an issue here.

3: vixxx: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue
state DOWN group default qlen 1000
What interface is this? It looks like a dailup connection?

Correct. Thanks. I'll strike-through the DNS.

The reason I suspect it's an ISP issue:

I have similar problem time to time -- not now, and not necessarily FreeBSD.org.
For example: I visit a site e.g. example.com. It's not blocked, it always works (during a year).
But suddenly, with different machines, different OSs (FreeBSD, Windows) => I get similar error message, as OP.

My solutions:
All machines, same settings, nearly same time:
* I switch the 4G/LTE carrier. ISP A to ISP B => problem solved
* If I use VPN it get resolved too.

Hours later, the site is back to normal. I use it as a kludge. Not sure about nature of problem, and also those two solutions.
My best guess: something is wrong with ISP.

Router hiccups, e.g. routing table screwed up on an regular update. Some time later, the tables got fixed on the next update, or the router rebooted by the ISP's friendly service staff.

The access issue is persistent. I have been trying for weeks. The wired connection and it's wifi blicks forums.freebsd.org. Screenshots from a moment ago.

This is clearly an issue to report to & ask your ISP about.

Can you PM me your IP address? I can verify if it's blocked or not. But as I said, we have a number of blocks that are due to abuse or spam. It's possible your IP address falls into such a blocked range.
