I was debating between speaking up about this or just let it go. It's a relief I wasn't the only one, although clearly that didn't keep Mr. Drax from sending me abusive private messages on my Facebook throughout the day, which is for my RL stuff(which I admittedly do have linked here) and where I barely ever discuss SL at all.
After I calmly explained my viewpoint about his 'opt out' style marketing, he went on to insist that his practices are not spam and then implied he would not be using my development services for further projects as a result of that feedback. What he neglected to mention though is that we've been passing acquaintances within the solution provider community for about 4 years and I've discussed my misgivings about this more than a couple times when he's spammed me in the past. If he had intended to employ my services at any point previous, he would have, so empty guilt-trip is empty.
I really would have preferred that he address his negative PR
issue publicly on the forum, but apparently he is too big for that. I have forwarded him a link of this thread though. Perhaps it will come to some positive end.
