Maybe cuz they only want to tweet to people they are comfortable with?

Why would you assume online privacy does not apply to providers?  Social media is a double edged sword, some providers have personal accounts they don't want attached to the work account. Also, some have accidentally mixed the two accounts. While it is an excellent marketing tool due to it's social nature,  being careful never hurt nobody either.  

FYI, your posts are getting dumber by the minute. This one was plain fuckin stupid.

why are you so angry?  It's their account and they can do what they want with it. How does that effect or offend you?
And obviously this is not a normal "9-5"(duh) job.  But it is a job if we treat it that way. Some girls don't care about their reputation, but I take this seriously and take pride in it, and since I try to always find ways to improve and am passionate about it, it is a job...i don't just lie there. If I did, I wouldn't be successful. It's physically demanding (which is good cuz it keeps me in shape lol), and it is all about customer service (something which I suspect you might not be so good at), among other things.  Plus, hello!.it's what I do to make money. That's the definition of a job.
A couple other things I want to say:  it does matter if other people found out, as I do have people who I would not want to know that this is what I do.  Also, you are wrong in saying that it's so easy for a provider to start over lol.  You don't know what you're talking about.  It takes time and hard work to build a reputation!
Also, your little quote about not giving a fuck and "I'm tr mofos"...is pretty funny. You seem like you're trying hard to seem cool and it has the opposite effect.

Next time try asking a question if you don't know why something is done.  Going off the deep end for no reason makes you appear like this guy:

I dont follow them on facebook because other can see my friends

I call this provider she want a pic so use my smart phone and she save my number on her smart phone she went on fb it add all her contacts as friends.

The point of a provider having a presence on social media is that it's a form of marketing.  Seems to me that allowing unrestricted access to FB, Twi**er (are we not allowed to mention social networks by name on these here forums now?), etc, is in the provider's best interest.

If I stumble across a mention or re-tweet of a hot-sounding or hot-looking provider, and then go to her social sites and find out that I have to ask for permission to follow, it's really kind of a turnoff.  The marketing did what it was supposed to do, and got me to look for more info about the provider; so I did that, and now I find out I have to jump through hoops just to "follow" her 140-character nuggets of wisdom?

Then I start imagining how much of a hard time she's going to give me in the screening process--and then I imagine she's more likely to be BSC ("Oh, check me out, I live in public, follow me on my social sites...but only if I already know you."  Wha.....?  What the hell is the point of being on social networks at that stage?).

Here's where RT is wrong, though:  If you're worried about having your social accounts linked to your "real life" just set up a second Twitter account linked to your hobby email address and hobby phone.  This is not rocket science.  I have half a dozen different "identities" on social media for different purposes.

fwiw, I assume that any providers who wish to do so, also have multiple social media accounts, with one being "professional" and the other "personal"--now if the provider wants to protect the personal account, that makes sense to me.

REASONS TO HAVE A LOCKED TWITTER ACCOUNT:
1) people like RT aren't good at hiding and we can make sure they can never see what we have to say
2) children can't follow us
4) pervs looking for jerk off material can't follow us
5) pervs looking to steal girls pictures can't follow us
6) creepy ex clients can't follow us
7) creepy potential clients can't follow us
8) random creepers can't follow us
9) crazy fire and brimstone people can't follow us
10) most importantly, it keeps us out of trouble with Twitter. They have rules, if you ever bother. And they are pretty lenient with us.  

We don't do porn. This isn't legal and we aren't trying to get every Tom, Dick, and Harry to click on a link so we can get a couple of penny's for the website hit. We don't need that level exposure, and a lot of us don't want it. Marketing is important, correct marketing for what you're doing even more so.  

Some just check that you're not a kid, some need to have seen you to let you on twitter. Both and everyone in between is just trying to play by the rules and avoid the crazies. They are ton of people on twitter, no need to interact with all of them!  

(End of me trying to be educational for everyone else)

Tucky, Everything you need to see should be on her website. You don't need to see her twitter and this whole "marketability" rant is just you stomping your feet over not being "free" to find something else to be angry at a provider about. You are the perfect example of why a girl would protect her account, honestly. You're not actually on twitter (no, you were not following that provider), you're not actually going to book an appointment, you're just looking for jerk off material, and you are an overall angry, hateful person towards providers. What about exposing ourselves to you is good for business? Honestly? What would the point be, other than to feed into your next half cocked "stupid hookers" diatribe?

Why does shit like this need further explanation?

Besides, if a dude decides he won't book with me because he can't read my Tweets without sending a follower request, I'm pretty sure I won't lose any sleep over it.

I've got a Twi**er account

that I barely even look at. If anyone wants to follow me it's the same name as it is in here.  However don't expect a ton of activity.  I look at my email and on here practically every day, Twi**er not so much.
