>3taps does not now scrape craigslist’s servers, and therefore, cannot be in violation of the CFAA
This was my understanding of how their system works. CL (for their own benefit) allows other sites to index their content. 3Taps indexes from the cache of these sites, thus never touching CL's servers.
Now as others have said, you got banned by walmart, now you're sending someone else to buy stuff for you...no more trespassing issues.
