One would assume so, going by comments day in, day out, on MN. Also from three of my friends who have had dates with men who:
a) walk out of the restaurant and stand smoking outside the window
b) swipe through Tinder when the friend got up to go to the loo
c) talk non-stop about Arsenal
d) insist on going to Nandos
e) have a cheeky this, a cheeky that - everything was 'cheeky'
f) ask them on Date 1 to tell them all about their exes
g) message when en-route to the first meeting to say they wanted to 'take a rain check' - this was in a city between both their hometowns
h) ask for inappropriate pictures
That's enough to be going on with.
I am of the opinion that anyone with anything about them wouldn't need to go on these sites (these friends all met partners, one actually on Tinder the others through a fell running club and a mutual friend). So the apps are packed with these ghastly weirdos who see it as entertainment.
