I'm not actually blonde, but I have my moments…
For the past two days I was cursing and cussing the annoying property of BHW forums that even if you ignore someone, they can still send you private messages.
A moment ago I figured out however that ignoring someone doesn't automatically close all previous conversations you had with them, and so you have to go see your full format inbox, select the item, and from the moderate dropdown select leave.
I am a humble agent of lord MP of TMSR (of fuck-you-SEC fame, of ETHrape fame, of saved-OpenBSD fame and so on).
So far in an exploratory phase, but as my master has deep pockets indeed I expect something may well come of this.
