why do my posts need to be approved?

My posts do not show up instantly. This is getting annoying.

Why is this? Does someone want my passport to prove that I am not a bot and spammer?

read forum rules. Comments beeing approved until you got 10 Posts.

I can’t find the forum rules. Perhaps you want to put it here as well?

Ah, found the forum rules here:

But it doesn’t say that new users will need moderator approval for each post. I am sure you will disagree but can you show me the exact passage where it says so. I think it needs re-formatting.

you are right, there is no word about moderation for new users, just that they have limited rights.
