IUseBrains-
Please don’t take offense, but you seem like the kind of shadchan that my friends and I had to blacklist.
When a shadchan gives a girls name to a guy it is up to him (and his parents) what to do from there. My mother told one shadchan to never call her back after she said “you think you’re being farfrumpted, well you’re being farcrumped. You have to tell me why you’re saying ‘no’. I’m a professional shadchan and therefore the issur of Loshon Hora doesn’t apply to me. Stop being a chanyukkel on someone elses cheshbon.”
(My mother worked with this girl and had wonderful things to say about her (including that there was nothing wrong with her) but she knew her well enough to know that she wasn’t for me.)
Who are you to decide what is unjustified? What is important to one person may be a non-issue to someone else and vice versa.
The shadchanim need to learn to be civilized or they are ruining the chances for many girls who otherwise may have no access to guys in yeshiva.
(If the guy and his mother are harrassing you non-stop to find him a shidduch and this is how they are acting then I see where you are coming from.)
