I have no personal information to share, but he's been previously discussed here:

He looks HAF and we need to quit this nonsense about a person's age. Beauty and talent is not the province of the very young!

It's now under the same name as his deli ad.

@PetetKsfo did a great job of explaining this. There is a option to set "Availability" and "Not Available" is a setting that the guy can toggle. The default is "Not Set." Here's what it looks like:

If the guy chooses "Available" or "Not Available" he then needs to specify a timeframe, anywhere from one hour to one week:

So as Pete mentions, setting "Not Available" would indicate the guy is not available right this moment, but is otherwise available at other times. It's a more short-term option, compared to freezing or hiding the listing which would indicate a longer-term absence or limitation.

I can set my status to "available"  "not-available" or "not set".
"Not set" is the default setting if  I am offline.
Once I log on, the setting changes to green and shows as "available"
I can also manually set myself as "available" so even if I am not right at the computer but cooking or doing laundry or something, I can keep the "available" light on for up to 6 hours.
If I know that I have a client booked in the afternoon, or if I am not available at all for a day because I have some other plans, I can change the setting to show as "not available"  - either for a number of hours, for a day, or a week - in order to not waste your time if you are looking for something right now.
So I would say that if you see a "not available" - it means the person is not available right now, or probably not for the next few hours, but may be available later or the next day.

Not knowing exactly what you're seeing, I can't offer an opinion, but here is an older discussion on what appears to be the same topic.

Most search engines require at least three characters for searching to limit massive numbers of irrelevant results.  A quick test indicates that is true of CoM's search.

Same ole story. If you think he's a beauty, he hits all your buttons, he performs well and you're willing to pay his price then you hire him. If you refuse to pay more than $X under any circumstances then you keep looking. We sometimes get stuck on the notion that everyone should charge the same rate regardless of desirability and performance. There are all sorts of price points in this enterprise. There are all sorts of customers. BMW and AUDI cost more than Chevys. Yet nobody says they are all cars, or a car is just a car. 

I don't have any specific desire to be with a straight man just because he's straight, but I also don't care if a provider self identifies as straight.  I have hired providers who have identified as straight, bisexual, and gay.  What I care about is that I find them attractive, and they agree to what I am looking for when we discuss meeting.  I almost always check here (and previously on Daddy's old site) to get reliable information on others' experiences before I contact them.  I have had some great experiences with guys who identified as straight, and some not so great ones with guys who identified as gay.  I think you just have to do your due diligence and hope for the best.  And if they deliver on their promises, tip them well.

Of the many chaperos I hooked up with at Sauna Thermas, two of the best kissers were straight.  Holy sh!t, did they make my toes curl!  I couldn’t care less if they were gay, straight, or Martian as long as their tongues turned me on.  When I hired one of them for a 5-hour evening, it was fantastic.  I knew his limits beforehand, was fine with them, and we both managed to have a great time.  Funny, I wouldn’t call it a boyfriend experience, more like a friends-with-benefits experience.  Conversation was so easy with him, like we were best friends from high school, with the fuckbuddy angle thrown in.
Like you, I’ve hired some real duds who were gay.  I didn’t hire the straight Thermas guy because he was straight but because we clicked so well on the premises that I wanted to see him offsite.  Whaddya know, he turned out to be one of my best hires ever.

My former partner was a successful hairdresser. He would always say the customers who tipped the most received the best service. However, that didn't mean the biggest tippers stood among his favorite clients. It's a funny thing how that worked.

Or as a well-known British entertainer once said, I'm bisexual, I buy sex.

I identify as bisexual, because I will have sex with BOTH gay men and straight men.

Thanks, but if I need your help, I'll be sure to ask for it. Things turn me off on women as well. I guess I just fear everyone. Sorry, but if I hit a nerve, I'm not the one who needs help dealing.

Kissing requires chemistry, which is recognized only when face to face. Never assume it will be included, even if they say they're into it. But always show up with your mouth freshly douched and polished. 

I met up with him a few years ago when I was visiting NYC and he was there as well. So I swung by his hotel. Insanely hot guy. We hung out for a few drinks at his hotel and a chat first. I was taken aback by how friendly, relaxed and nice he was though (it’s often more often than not something you expect from these really hot guys). I found the naked session SO hot. Looks incredible with his gear off. The kissing was scorching too. 
i was hoping to meetup again on further trips to the US since then, but the locations never aligned for when I/he was there with him travelling. He needs to coming out to Australia for a visit!

I don't think anyone can say who is or isn't STD free.  You can't go by what is on the profile either - providers can say anything, or may not be aware of their health status at the moment.  So please ensure you protect yourself for the level of risk you are prepared to take.  

I've been with Dillon on multiple 3 day trips.  One of the nicest guys you'll ever meet!  The 1st time I met him I  picked him up at the airport and without even seeing a face pic, I knew it was him...huge muscular body and insanely handsome!!  He's very affectionate and a great kisser!  He's NOT arrogant or sneaky (whatever that means).  And he doesn't talk about himself alot.  He's a great conversationalist.  I would highly recommend him!  You won't be disappointed!  And when you're out in public just be prepared because he turns alot of heads looking at him...both men and women!!
