Is it okay to share helpful fan resources like Bus Simulator guides?

I run a fan-made resource site for gamers, where I share guides, maps, and safe downloads to improve gameplay. For example, one of the most popular resources is Bus Simulator Indonesia MOD APK, which many players use for a better experience.

Before I post in discussions, I want to ask:

Is it allowed to share links like this if they’re directly relevant and safe?

Should I only share guides, or are mod/OBB resources also acceptable?

Any rules to make sure posts don’t look promotional but stay helpful for the community?

Thanks for clarifying!
