Go to the front of the blog and on the gray Admin bar locate the drop-down on the left hand side click "report this content" and carry through.

If you are publishing a blog that you expect will contain content that is intended for mature audiences, we ask that you provide us the courtesy of reporting your own blog by using the Report as Mature option in the blog menu of your Toolbar. http://en.support.wordpress.com/mature-content/

If a adult blog is set up on WordPress, is their a feature where the user accessing the blogs address will first be asked to confirm they are over 18, like on Blogger too?

There is no such feature here but you can create a static front page.

"Adult" or mature content blogs are allowed but pornography is not allowed.
From the TOS http://en.wordpress.com/tos/
Please don’t:
•Post explicit sexual materials that can be considered pornographic, such as explicit images or video of sexual acts or close-up images of genitalia;
•Post links or banner ads to adult-oriented affiliate networks, such as pornography site signups;
•Post links, text, or images promoting or advertising escort services;
•Post images of extreme violence or gore without associated context or commentary;
•Post images of child pornography;
•Post content that promotes pedophilia, such as blogs with galleries of images of children where the images, content surrounding the images, or the intent of the blog is sexually suggestive.

We do not have age gates at WordPress.com.

What is Mature? If only it were easy to say.
Lots of profanity - probably.
Some profanity - probably not
A few images of topless women (for it is usually women and western society tends to see the topless man as non sexual generally) - probably not
Lots of images of topless woman - probably
Genital images - definitely unless the blog is educational (and yes, we know the difference between education and not)
Images of mutilation, dead people, injuries, cruelty, killing - definitely.
Combinations of the above - probably
Declaring your blog 18+ - definitely [emphasis added]

When I started the blog, I seem to recall the set-up asks you to indicate an age range. Am I imagining that? It's possible...it was two years ago, and I'm getting forgetful in my old age... ;)

Also, I noticed in the links forwarded by timethief that if I marked my blog as "18+," then it automatically is flagged as "Mature." Given my initial understanding of "adult/mature" content, I most likely marked it that way initially -- even though, almost two years later, I've definitely not included anything worthy of that distinction. I don't see this setting in my dashboard; can you verify that my blog is NOT marked as "18+"?

Thank you again!

If you ever feel like you've crossed into an adult-only territory (in accordance with our terms of service, of course), please feel free to report it again.

@macmanx: Thank you. You guys are fast! So now that I'm looking into this, my blog has been labeled "adult/mature" and may not actually embody that classification...is there any way to remove that label?

Hedgehogs is "Mature" because of language. Blogs that include swear words on some posts do not belong in the same category.

Freshly Pressed isn't randomly generated, one of the staff members choose the content that goes on there. I agree with that level of profanity, the post shouldn't be on Freshly Pressed where younger users can view such posts.

Many of us bloggers mark our sites as "adult/mature" because we use foul language -- in my case, the reason I've marked it "adult" is primarily so my children (and any children) won't be able to access the site on computers with adequate parental controls. This just seems the appropriate thing to do. Of course, we do this knowing full well that this most likely precludes us from being "Freshly Pressed" per your "How to" guide to getting Freshly Pressed (http://en.support.wordpress.com/five-ways-to-get-featured-on-freshly-pressed/).

In this post, your support team indicates that rule #1 is "Write unique content that’s free of bad stuff," adding "Each post that makes it to Freshly Pressed contains original content created by the user. Bad stuff includes (but isn’t limited to) plagiarism, hate speech, fear-mongering, adult/mature content [emphasis added], copyrighted images that belong to someone else, spam or content that’s primarily advertorial in nature."

I would argue that "adult/mature content" that is simply not excessive foul language should NOT be excluded from Freshly Pressed consideration. Of course porn or sexual discussions should...but swearing is not exactly "bad stuff" to most bloggers. Yet WordPress groups that in. Or at least I thought it did.

So you can imagine my surprise -- and probably hear the collective gasps of all blogger/readers -- when we read this today in a post titled "On gaining and losing friends":

"Then I realized that [removed] and has been hurting and re-hurting me for the past 18 months."

This is so discouraging. Clearly this blog has not identified itself as "adult/mature," despite the BOLD (yelling) of extremely foul language. Is someone on your team screening for this type of content?

I just wish WordPress provided a level playing field with fair opportunities for Freshly Pressed exposure. Either make it so that foul language can't be Freshly Pressed...or make "foul language" an exception to the "free of bad stuff" rule. And really, today's post pretty much contains the foulest of foul language. I'm a woman who sometimes swears like a drunken sailor, yet I would never use this language...

Can you provide any clarification about this? And if I choose to "unmark" my blog as adult/mature -- is that even possible? Because yes, I swear...but not even CLOSE to the level of foul language that this blogger wrote in today's Freshly Pressed post. Perhaps I need to reconsider.

Thank you in advance for your time and help.

I read the link you provided me but I am a bit confused. I would like for people to find my blog except for those closest to me in regards to family, children, etc; but I do not have specific user names of who I want to access my blog.

I would like search engines to find it as well.

I hope I am not missing something in the link you gave me. I am off to watch the video and see if that can help me. I simply don't want the two blogs of mine linked together.

@ airodyssey- thanks for the link, although I am aware of the mature content setting. I just want to make sure that people can't find it off of the first blog. It's easy for someone to click through the mature content warning (unfortunately)

There is my URL, I am just starting it and I won't be putting anything on it until I can figure out how to set it up right.

Thank you! :)

@rglee98: Yes, but you should also read the first bullet here:
