Guys, What Is Your Experience With Online Dating Like Match.?- Is It A Waste Of Time? Are Women Too Picky ?

I have written alot of women and very litlle success ? is it just me ?
Are there alot of scams on the internet just trying to get money ?
I noticed some women say they are in Africa or russia..
Do women just get too many offers thast for guys it is a shot in the dark ??
Any feedback or input I would appreciate….
