@Curious . . . well . . . and others.
Why are you assuming that everyone is __________ (out to get you, fake, or something else negative) Try a different perspective and things may be easier. You do not know what is on the other side. You only know what little you can decipher in a generally terse message. Why are you assuming the worst?
My wife is on here . . . oh . . . about 20 minutes a year. She has other shit in her life to do than this. When I communicate with people, I use the word I almost all the time. I do not mislead by trying to be pleasing that it is both of us. I am explicit in stating that it is me and me only. I also state that my wife rarely spends any time on the site. Does that make me a terrible person, a fake account? We are far from that. For those that are afraid of leaving the confines of this safety net . . . Really? Uhh ok. Here is an example for us. How would you have handled it as us, and then as the other end. My wife is traveling in a few weeks for a few days. She would like some SM company where she is going. Her and I sat down and for 5 minutes, looked and found a few that piqued her interest. I took over from there. I stated who I am and that my wife was heading to the area. I asked the person to look at our profile and pictures and see if they think there is a match. A few replied yes. I then said, as I told you my wife is rarely on here. It's not instagram :) Her is her cell #. Text her. See if there is any chemistry/compatibility. I told them sending messages through here, would just result in me seeing it and her probably not. It has worked for us.
As far as pic collectors and your kids seeing it . . . this has been our experience in that regards. If you have been in the lifestyle for a while, chances are your kids already know. I know . . . you are so prim and proper around them and hide everything. You don't hide your behavior change. Your kids talk to other kids. Your kids see other parents behavior. Your kids compare. Your kids will wonder why you only know some people by their first name only. They will figure it out. Give them credit for being smart and observing. We have been in in the lifestyle since the mid 90s. Our child knows. It took a little bit, but our behavior compared to others as well as constantly going out on weekends and talking about people that our child never met all gave it away. If you are doing something that you think is embarrassing then you should not do it. You have other issues. As far as being outed, well, fuck, we were on HBO's Real Sex, episode 16. Our very good friends were on Oprah for an hour. Yes. Both about swinging. The ramifications for us, a few business contacts saw it, my wife's sister saw it, a few friends saw it. The impact was a few calls and that lasted all of 10 minutes. No one gave a shit. My gay barber saw it. He was cutting my hair, asked me some opening questions and then said, "So, I was lying in bed the other night, watching TV and . . . YOU SHOWED UP on my TV." Oh well. He knew that we were on TV, he didn't know exactly what we did and with whom.
Pic collectors, well, are there some? Yes. How often? Rare. Is there anything you can do about it? Other than never having any pictures there is no way to stop anyone from collecting your pictures and doing something with them. It is the risk you have to take. If you aren't willing to risk that much, well, you will probably not get what you want from this site :)
Unless you have a job that has a morals clause in the employment contract, there is not much to concern yourself with.
