Can we trust him?
Security question is very important for bitcoin community.
A large history of bitcointalk.org show us that it is trusted.
But if in one day this bitcointa.lk forum will be hacked and all thread urls will be replaced by malware files, than it will cause money loss of many people. (For example download links for Qt Bitcoin Trader).
You should unflag this domain. (Not that it matters much)
It's a project that benefit's the forum as a whole...
