As advised in another thread: in hi-sec there is fairly good chance to participate in 1v1 duels and it is as safe from third-party tampering as possible since the neutral logis made to get concorded if they interfer with a duel.
I myself try creating a new initiative regarding this in the form of a duels channel and also a public brawl event (and also participating in duels myself every now and then). To avoid self promotion and spamming I do not link the thread, you can look up my threads if you click my name and check my profile.
