I have been a member of SYD for a lot of years, under one username or another. My membership often expires because I have stopped using the site, due to the disappointment from receiving no response to a message or comment.
I have tried, complimentary, sexy and sometimes very suggestive comments. It makes no difference to most people. I always reply to any messages I receive, male or female, but even then that is the end of the matter. I exclusively compliment women, but also always reply to men.
I know most people only "look" on the site or the pictures of women are being posted by men, but it does help if we are polite.
