This happens sometimes google will get confused and give your site a much higher PR than it actually has. I really noticed this when black hat seo'rs found out that during a PR update they could redirect to google or yahoo to get a PR of 9 or 10. Give it a few months and the PR will even out once you have PR 6 for 6 months then it is solid. Also run your site through a pr checker http://www.prchecker.info/check_page_rank.php which is more accurate than your toolbar. Anyway if you are PR 6 congrats because your right up there with ezine articles and all the other top sites.
I dont think it is possible, with just 100 backlinks and PR6. Without checking the source of the PR/backlink, consider it fake too.
it is fake, There is no way the Alexa count would be over 10,000,000. You can surpass that just by visiting your own site daily. Also the information here: http://whois.domaintools.com/love365.eu It also takes about 20 minutes to open up.
