Does it happen when google finds your domain? If i was to buy a 4 year old domain that was just parked there and never made it to google, the chances are it will still get sanboxed right? Also when you are sandboxed do you still get occasional traffic from google? Thanks!
it happens to all new domains regardless of how they are promoted. It can also happen to a domain your buy and transfer from someone else, when you change the whois google re-sandboxxes (thats wot ive heard neway)
