Rule 3 is about “excessive” self-promotion. Self-promotion is allowed, spamming is not.

I understand it isn’t verry clear (I’m working on that), but as a mod, I usually do not remove if the following conditions are met :

• OP do not spam his game, once every 2 weeks is fine, once every two day is not.
• OP post objective is to spark a constructive discussion around said game. Good post forms are :
  • A video trailer that accurently depict gameplay (to filter those low-effort games whose trailers are 100% cinematics)
  • A text post that talk about the game without being just a steam description.
• OP ask for mods permission to advertise his game. @Road_Warrior_10@lemmy.world (sorry for the ping 😋) didn’t at first, got removed, but was nice enough to ask the mod about it, thank to what we found this arrangement.
• OP engages in the conversations. Those 1 day account that post their games, never to be seen again, will be removed without mercy.

All those implicit rules helps to keep this community free of advertisements for low-effort cash-grab games, and preserve everyone enjoyment of this community.
