I've always check the lost and found because of the enormous amout of
Pets that are lost. Now the lost and found site has electronics for sale.
Something is messed up. So I contacted Craigslist twice and never got
A reply. I'm sure others have written in. Do you have any idea how I
Can reach a human being on Craigslist to let them know what is
Happening?

In all honesty, if you have already mailed them a couple of times I would leave it at that.
A real person isn't going to be able to assist you any further.
