When I try to post a comment on a mod, I get an error stating "You cannot post links yet"... I have scrubbed the test all the ways I can think of to scrub it, even looked at the source and there are no links. This is happening on both Chrome and IE on two different computers.
I was having the same problem, so I just commented 5 times on a dead mod so that I could post links. I tried a bunch of different symbols that I was trying to use in my original comment to see if any of them were the issue, but they all posted just fine so I'm still not sure what was actually preventing me from posting.
