Does Whois Guard affect SEO?

I have been reading about spammers usually using whois guard, so Google tends to give more trust to websites not hiding their info on whois. So I tried not to use WIguard. I was spammed to hell in a matter of days, and what concerns me the most, is that my phone number and full name are on display. Rookie move - I know. So I activated the guard on namecheap now, and hopefully my details will vanish soon. What I'm wondering is: is there any truth about the whois guard/SEO correlation?
