Why isn't this being done in a transparent way?
RPG.net is garbage, but at least they're open about their draconian practices: https://forum.rpg.net/forumdisplay.php?138-Infraction-Forum
Re: the inevitable "we don't have the forum tech": Unless the forum tech is much more limited than is common, it should be possible to create a subforum in which only staff members can post for the purpose of detailing bans and thread locks.
Yeah, it'd require some effort on your part - manually posting about each action - but severe acts of moderation should be rare and treated as a serious matter - taking action against your own customers - deserving of explanation (even if only as much as RPG.net gives).
This will enable us to better see whether or not moderation is biased, and make clear what is actually being moderated on a regular basis.
As it stands, I buy some games I intend to play right away but also spend a few dollars in most sales just to support GOG as a force for DRM-free gaming. I don't plan to boycott, but if GOG abandons its general commitment to open expression, if you go full-on PC police, you can count me out of the forums, and you can bet I'll be scaling back that support and spending a lot less money here.
Also, here's a blast from the past, the thread I made when I first chanced across RPG.net's infraction board
in some search results.
