I specify right in our profile that the male half does 100% of the online interaction. People tend to draw a blank on what to put in the Additional Comments section of their profile. This is probably not a bad thing.
It's also clear at times when SMs reach out and assume they're chatting with the Mrs that they haven't bothered to read a profile.
One thing that isn't a red flag, but kind of a hot button for me is when you see these guys that try to leverage being in the service to getting special consideration. One case of that was a guy showing up at a Halloween party in his fatigues and expecting girls to "thank him" for his service. All I could think was that it's kind of an insult to the uniform to treat it as "a costume".
Had an SM reach out a couple days ago and make it known that he was in the service. Unfortunately he also unknowingly made it known that he hadn't bothered to read the profile because he assumed he was chatting with the Mrs, among other common mistakes.
