I have been locked out of both class forums and ability to submit a ticket

I have been providing feedback on the LFS144 course in the forum in this thread. I identified quite a few typos and have been providing feedback. I was just authoring another post that included text copied directly from the course web page. As near as I can figure, because that copied text included HTTP tags, when I tried to preview the post I got flagged as an “attacker” by CloudFlare and was blocked.

Apparently, that same blocking action ALSO denies me access to the ticketing system, so I cannot submit a ticket to get unblocked.

Help!

Apparently I’m also supposed to include this:

P.S., this makes me REALLY not want to spend time identifying and reporting typos. If I can get locked out this easily, why should I try to help improve the contents of the course?
