When I think of Craig, I think of Craigslist. And when I think of Craigslist, I think of scams. I see obvious scams. I see people begging scammers not to bother them while they try to sell their legit items, because if you've ever tried to sell something of any value on Craigslist, you've likely been contacted by a scammer.
I see people giving away and selling pets in every category. I see dating ads in every category. It is not uncommon to see someone selling drugs in any category. Whether or not you agree or disagree about people's ability to make these kinds of ads is not the point, the point is they're a mess and contribute to craigslist's decline.
If you've tried to look for something to buy, you've likely been annoyed by loads of dealer ads that are mis-categorized as ads by individuals. This is because to post as a dealer, I believe you need to pay. If Craig can not even pretend to enforce this one thing, it cements them into the trash tier, because of the sheer quantity of these types of ads. I shouldn't need to point out that by letting this go as long as they have, it severely dis-incentivizes dealers who were willing to pay.
I want a viable alternative to facebook and ebay, and right now craigslist isn't it. So, maybe get your namesake secure, the thing that made you famous. Then, maybe people would consider taking your cyber security advice seriously. Don't just throw money at something you say you care about, lead by example.
