it depends on the subverse. Some subverses have a minimum requirement to post, some don't. That information is in the sidebar usually. To make a post you want to go to the subverse and above where your username shows up it says in a red box "share a link" to share articles/pics etc and "discuss" for text posts. Just an fyi if you are making picture posts use www.imgoat.com for hosting, you will get your head bitten off for using imgur here.

Yes, it also makes it so you can't earn CCP so make sure you visit /v/all/new or the other non-anon Q subs like v/GreatAwakening for example.
...and "(((they)))" could still track you. It's linked to one account and if your account was compromised all your "anonymous" posts would be edit/deletable.

I'll take your question at face value and assume you're new here. This is an anonymous board so everyone can speak their mind without censor or fear or reprisal.
