Well, I posted a suggestion here that was reviewed and not approved. Didn't break any rules, either, but was admittedly inconvenient for Apple.
I doubt it. Moderation in this forum is pretty rare. Takes them a couple of days to delete blatant spam.
It sounds like you had posted a link to a non-Apple website. That's a forum bug/feature. It doesn't allow using the link tool with a non-Apple link. You can still include non-Apple links. Just paste the link in plain text and it will be converted to a clickable link when you post. That does make sense. Otherwise, people could replace the text on a malicious link with something nice.
Apple is aware of the "waiting for review" problem. I even got a reply in my thread about it. There's a feedback number and everything!
My issues are that 1) these posts clutter up the forum with identical complaints, and 2) there's nothing I can do about it. There are possible fixes in App Store Connect, like an estimated wait time, or a position in queue. There are possible forum fixes, like sticky threads, subscriptions, and private messages. There are possible Developer support fixes, like changing the boilerplate text to reflect reality, or actually replying to questions. But all that takes effort.
At least we have an improved editor window in the forum. Apparently it even supports attachments now?
