There's some spam in the #french channel: here • here (ads for their blog about optimizing LinkedIn profiles, nothing to do with Kotlin)

Always good to reply to the post itself and mention why it maybe shouldn’t be here and see how the author responds.

Well, it is neither about Kotlin, Gradle, JetBrains nor any other subject vaguely related to anything we could discuss here.

Yes I don’t disagree with you. I am saying that the first step is to talk to them, not ban them.

Messages should be removed at least maybe

Again, nothing should have to happen directly from admins before a simple discussion happens with the original author. Just mention that you don't believe these bring value in this slack channel and ask them to consider not posting more of them and possibly deleting these ones. Don't be afraid to talk to people 😅
