Still not showing on google

http://WWW.playhaus.com
Hi 3 months ago i posted a query re the above site not showing on google, even if i search “www.playhaus.com” and still it doesn’t show. I have logged it with webmaster tools, i have checked robots.txt; i have added myself to google+ and put it there and put it on twitter, etsy, folksy..I have tried to get it on google places but it just says it is being checked. It shows on bing, but only on bing. I bought the domain about 12 months ago, but i think perhaps in its past it might have been a porn site and is now since banned, i say this because at my husbands work it comes up as a banned site and when i searched yahoo it asked if i wanted search the adult content pages also.. Is there anything i can do to get this unblcoked from these sites or shall I give up and buy a new domain?
