Online dating is still a very safe form of getting to know someone. Learning extra safety measures can only be in your favor, and make it even safer, and more enjoyable for you. This advice will guide you as to when not to respond to e-mails, winks, smiles and any other form of communication.Receiving a flirtWhen another singles first sends you a flirt for that initial contact and they provide no other information. They should at least send you an e-mail first as an introduction.Most services provide smiles and winks on their trials before you’re allowed any e-mails. But these should only be used on singles that have at least browsed your profile.No photoWith today’s technology every member of an online dating service should have a photo on their profile. If they haven’t there must be a reason for it, and it’s probably not a good one. Even a photo of poor quality is better than no photo. If it’s very poor quality your judgement will need to come into play.Very brief profileIf their profile is only a couple of lines of text. If what they do, what they aspire to do and their interests are only a couple of lines what would dating them be like anyway.It’s just another sign that they could be hiding things or they really have nothing to hide what so ever.Nothing about youIf someone sends you an e-mail that looks like it could be sent to anyone. Where they haven’t mentioned anything about you and it’s obvious they haven’t read your profile. This could be an e-mail that has been sent to many singles just fishing for a response.What they wantIf they are not bothered what they want in a person they’re probably only there for one thing. So any singles who tick any or all, in what they are looking for, should be avoided. If they don’t know what they are looking for in someone then they shouldn’t be wasting other single’s time by contacting them.Cold callersSingles who grab an opportunity to have an instant message session just because they have seen you online. The only exception being – you’ve already browsed their profile or they’re following up an e-mail.They ask for a date immediatelySometimes you will get a single ask you for a date with their first e-mail. Avoid these singles like the plague. Anything could happen to you if you went on a date after receiving someone’s first e-mail. Avoid anyone that asks for more personal information that isn’t on your profile in their first contact with you. Again stay away from these singles.If you don’t respond to time wasters or singles that would be better off on an adult dating site your online dating adventure will be a very enjoyable one.
