that is a very weird response. who knows? A year ago, in spite of the many many judge judy/judge millian cases i've seen with problems stemming from craigslist, i tried to find an apartment to rent through craigslist. it was just a weird experieince. After carefully weeding through what seemed to be definite scams/weird ads, i responded to a few of the nicer ones (with details, with addresses, with photos, with names of people, with emails that were the "name@gmail" rather than the weird type ("kdklasjeiwojds@hotmail"). I got a few replies from totally different names, about different emails, telling me to send them more details about me (bank details, references etc.
OTOH - i joined a local hiking group that's bee around for centuries and they use the meetup app which i find very useful.
