Temi I answered your question perfectly. You asked if anyone knew, I said YES!
Now if you had asked me HOW to potentially avoid the ageing sandbox thingy, I would have told you stuff like. Don't launch a big site complete, launch it gradually adding content every day. If you have a large site to release, then release it via cron jobs on the cms.
Do NOT build bulk links, rather get a handful of high quality backlinks initially. Wait until these backlinks are spidered (cached in google) and then start gradually hand feeding the backlinks to Google daily.
Get your site blogged across its niche (if it is a niche) if not then get it blogged from on topic sites that have similar out bound links.
That is ALL y'all get for free
