The dudes and dudettes behind Opium Pulses have felt for years now that Valve abandoned improving the community features of Steam a long, long time ago in favour of features that directly earn them an income.
What this means is spammers have grown out of control and steam group owners are left clearing hundreds of spam posts a week, taking up a lot of free time. All it would take from Steam is disable posts from brand new group members for a certain peroid of time, but apparently even that's too much work.
We've therefore taken the tough decision to revoke posting permissions from members in ALL Opium Pulses Steam groups, something we never really wanted to do.
There is one social gaming platform out there that DOES still care about it's community though, and that's Discord[discord.gg] - if you haven't checked it out you totally should, starting with our server below <3
