We had it in place before the current mods came to the modteam, and it had never been a problem so far. It makes it less likely for people to breed resentment and start wank (concrit) and also works as a constant love meme (poscrit). We've had very few complaints if any ever since the HMD was set up -- on the contrary, people have often told us that they like the system -- so there was no need to remove it. And it also opens the mods up to suggestions and stuff that would not normally be given. The game-wide HMDs are f-locked only to the community, so only those playing in the game are capable of seeing and responding.
