If you look at the bottom of the page, in addition to "Guidelines" and "FAQ" (which you should read) there's a "Contact" link that allows you to contact the moderators. They're nice people, so if you can convince them that you'll use the site differently from now on (e.g. posting less of your own stuff, posting more of other people's stuff that you came across randomly and found interesting) they might decide to make your submissions visible again.

But if you don't want to change what you post about, it might be a better idea to look for some other place to post it.

I'm not sure why it was downvoted, because dang posted very similar advice in the past. (Perhaps the tone is a little aggressive?)
