As others have said, not sure what problem this is solving, but meh. I'll post when I have something to say and the time and energy (of which, I have less than I used to) to say it, as always.
I had 100% positive feedback on a half-dozen transactions or so on the MM before access was taken away, so a.) I'll not miss it that much and b.) again, as others have said, you've reduced the pool of reliable buyers and/or sellers on the MM.
Either that or more pointless posts to keep up people's post count, on the pretext of "contributing to the community" - which is a highly dubious metric to measure anything - somewhat akin to measuring a software developer's performance by counting lines of code written!
Your house, your rules, but can't help feeling this whole thing has stirred up some bad feeling for little to no benefit.
