He says he just gets like junk mail from pof so that's why he goes on
I regret to inform you that this is a flat-out lie. POF doesn't send junk mail. The only way to get mail from POF, other than a monthly notice that there are new matches, is to request it in your mail settings.
The options are these:
Send me an email, when i have mail at PlentyOfFish: Yes No
Send me an email when someone adds me to their favorites: Yes No
Allow emails from Local Singles Events: Yes No
Allow emails (first contact) from users without images on their profile: Yes No
The last two may apply only to within-POF e-mail, I think. Anyway, I have them all set to "no," and I don't get any e-mail from the site except a monthly note that there are new matches.
If he's getting mail from the site it's because he asked for it so that he will know when women e-mail him or favorite him.
