So I read the first two pages of a thread, and when I clicked on page 3, I got an error message. Sorry, I should have written the text down, but it was something like, "You don't have access to this page." I went back and tried again, same thing. Then I went back to the main page for that category and I think the thread had disappeared. It had been almost at the top of the page and when I refreshed I didn't see it at all.
Just from what I read it seemed like the thread had the potential to get heated, so I'm assuming it was deleted by the mods deliberately. But I wanted to note it here on the off chance that it was a glitch of some kind. (The thread was in "Family and Children" and involved swimsuits.)
