To me, Craig's list is officially taboo
I've made quite a bit of money on CL selling tools & machinery and yes, the foot traffic just isn't there anymore. I tried OfferUp, but I really don't like the platform -- it's too much of an app and I'm more of an analog guy. So, I'm left with tolerating FB.
The folks who complain about getting the code requests and scam messages on CL just don't understand that it's not a real person sending those messages (it's a bot, as in robot). So you can type in your ad that you won't respond to code requests all you want, but the bot won't read it. You'll still get the scam message. Just ignore it and wait for a real person to inquire.
While the FB "Is it still available" is highly annoying, it's just par for the course. It takes 2 seconds to reply "yes" and move on with your day. If they're a serious buyer, great. If not, wait for a serious buyer.
It's a sad fact that this is what our flea market culture has devolved into, but if you want to sell your junk, that's the muck you have to walk through. Or you can do like
@Princess Valiant and load it all in your truck, light it on fire, and roll it down a hill.
