Things about online dating:
10% women and 90% men, so you have to be at least in the top 20% to get any matches / replies and be very proactive in texting
Being a 7/10 'nice guy' will get you nowhere in the online world
Everything is about your pictures, both how you look and the environment that they depict (indoors, outdoors, vacation, among people, work, artsy, etc.)
Height is very important, 6ft or you will be judged
Women without body pictures are overweight, it's the law
Women tend to use selective or edited images to exaggerate their looks, men do that with height and status
Women in their 30s lie about their age
Many women are there just to get attention from simps, ask for an irl date early on to weed out the time wasters
Beware hookers, fakers, cam-girls
Overall online dating for men is mostly disappointing. I have been on ca. 20 irl dates so far and real world experience is much better.
