That smudge between "make" and "law". Was that an ink drop on the original? They are also trying to figure out why the Founding Fathers skipped from Amendment VIII to Amendment XI.

There are no absolutes. The FEC could rule that slander laws apply to internet bulletin boards and believe me, there is plenty of slander going on, some at FR and more than that at DU.

They could also rule that poorly worded comments be banned if they could be construed to constitute a threat to someone or some thing.

They could also rule that NO copyrighted material of any kind be posted.

They could also rule that no material from FR be reprinted or reposted elsewhere.
