I don't care if you are the Chair or not. Do not use your position to accuse someone of personally attacking someone when they are not. If you were being a fair Char, then I'd also expect you to deal with your friend Randys passive aggressive insinuations - which you never do, so just back off.
I suggest you go research Lu's posts on ARIN and Ripe over the last year and you will see the antagonistic approach he uses to turn lists into battles, including attacking the Chair when he doesn't agree with them. Is this what you want to happily let him do to APNIC lists?
I for one thank Owen for informing us that Lu was trying to start the same/similar arguments on this list has he has done on other RIR lists. I hardly think we need to rehash the same debates unless they are particular reference to APNIC and its policy.
As the Chair, let me warn you that calling somebody "trouble maker" on the list is a personal attack and it conflicts with APNIC Code of Conduct as shown in below.
