SharePoint object model won’t help in identifying WHO has created a web site and WHEN it was created. However, a little sneak peak in the SharePoint content database will reveal this critical info.
Here is the sample SQL script that will show the user and creation date of any given site:
1: select u.tp_login, u.tp_title, w.title, w.fullurl, w.timecreated, w.lastmetadatachange
2: from webs w, userinfo u
3: where title like '%<site title here>%'
4: and w.author = u.tp_ID;
