I'm not a DT member like Vod, so I'm sure I don't get anywhere near the levels of unsolicited PMs that he does, which means that for me, if someone sends more than one when attempting to engage in a discussion on forum related business, then I'd be inclined to call it spam... or if it is obviously "spam" like trying to sell me something or promote a website or service etc. For Vod, perhaps his threshold is ANY unsolicited PM == spam?
I still stand by my comment that the reason for your negative trust is quite clearly explained in the comment... it was "Begging for merit in unsolicited PM".
You may not be a DT member but you've got that intelligence to outweigh some people in that position, I appreciate. I would not say "outweigh that position" because that position is respectable and we should respect that position.
