deleting offensive content from teams free

hi Teams Community!

I'm running a community using Teams free and now puzzling on the following issue: suppose someone from community posts offensive message (let's say racism speech) - I can delete the user from my teams account, but the content (posts in channels, files) stays there. 

It appears to be there's a setting in Office 365 admin which allows admins remove other people's posts however it is not available in Teams free. How do I workaround this problem with removing offensive content?

I know, I can remove the entire channel but this is obviously hardly an acceptable scenario for a community (because it removes all the other legit content).
