As I have now responded or not responded to messages from ads for many years on this site, I would like everyone to stop for a moment and think. I know we are all here for our different fetishes/kinks. That's good: so am I. Many of us have put up ads, looking for a play partner, someone to chat with, etc. Which is also good: so have I.
When reading and responding to ads, take a couple of minutes to really read the ad. What is the person saying they are looking for? Is it what you think might be compatible with your desires as well, or are you projecting your desires onto their wording? Have you taken a look at their profile? If not, do so before you message someone. Don't just look at their “wall of interests”. Read their intro, if they have one. Look at what kinds of posts they've liked, and more importantly the answers they've written to their posts.
If you still like what you've seen about the member, then respond to their ad, but be polite, respectful. Introduce yourself, tell them what intrigued you about their ad, and request the opportunity to chat. If they then respond they are interested in chatting, get to know them, not just why they like XYZ kink and about their personal life. Building rapport will go a long way towards a more pleasurable role-play, whether online or in person.
Roleplaying, Chat Gram, Chat Room, Private Message, In-Person play… let's treat each other with respect. Treat each other with courtesy. And read their damn ads to understand what they're asking for!
