Well online dating is now common and everybody put his self their to chose his perfect one, but somehow its just can be pain for you forever, so never trust anyone blindly, everything looks good in certain limit.
so if youre dating someone then make sure, your not giving your personal pics that may cause you a serious blackmail in future, if anything happens, so dont put your pics and phone no .
these are dangerous too, well I used to stay a lot, and everybody learn from mistake but I suggest you to no need to learn from mistake, learn from your self.
that is my opinion for online dating
