Try it again. I see it. I saw it about an hour ago and trying it now, I see it, too. You're going here, correct? : facebook.com / Tektondesign
Yes, that's where I went - still seeing "content not available." I also tried accessing it via Google - searching for "tekton design facebook" - a I got multiple search hits, for different countries/languages of Facebook, and all of them gave me the same "content not available" pages, in various languages.
I also went to my Facebook activity log, comments section - and it shows notices of all the comments I've posted in threads on Tekton's page, but unlike with normal comments, I cannot see a summary of my comment, and I cannot click on any link to get to my comment in the actual thread.
I think what's happened is that
@Eric Alexander (or whomever he has running the Tekton page) has blocked me from the page - and I would assume he's blocked multiple people who have posted critical comments on the page. I wonder if that includes
@amirm ?
(EDIT:
@kschmit2 - I'm sure you are correct; I was typing this comment while you posted your comment just above.)
