Well, the moderator approval thing won't go away for some time but if you're wondering why your other posts haven't shown up, you are trying to link to a banned website.
e.g. if your post shows up as https://******.com for example, then it's not gonna make it through the approval process.
So what you need to do is upload the image somewhere else and try posting it again so that it is acceptable, will get approved and so that others can see your posts and start helping you.
And you must've had some joy on the profile pic changing front, because you've now got a plain grey image for an avatar which you didn't before.
