Opera says it uses Netcraft, Phishtank and Haute Secure for to check site security. As far as I can see you can't make changes to that setting. I went to those 3 sites to see if they had listed us but, aside from Haute which wanted me to sign up to stuff, things seemed OK.
I left a comment on the relevant blog asking the guy to contact me with further info about how he got that info. Beyond that it seems that FTG is coming up fine for everyone else, so I might stop worrying about this.
And thanks Simon
