With people I don't know, it is when I've replied to an ad on craigslist through craigslist when there is no other contact information. Three times in the last year I've replied to ads on craigslist for outboard motors asking for more info, and crickets, nada, zip, nil, nothing. How in the hell do they expect to sell what is in their ad if they don't respond to inquiries about their ad????????????
It's not like my questions are like the ones in the graphic below!!
UPDATE: did an ad on craigslist asking if the problem was craigslist or the people posting ads and in a couple days have had three replies to my ad asking what kind of outboard motor am I looking for. So the e-mail relay on craigslist must be working, at least in my case!!
ADDENDUM TO THE UPDATE: One of the ads was reposted and this time said e-mail or text. I clicked on reply and there was a phone number so I sent a text saying "Was interested saw your ad last month sent several e-mails no response no longer interested." Got a reply saying the e-mails went in the spamm box and automatically deleted and if I was no longer interested why the text. I replied, "I wanted to let you know I tried to contact you no response pissed me off. Got another reply, but I'm done with this.
