I’d encourage a change of labels away from “friend/foe”. It may seem minor but the subtle loaded nature of those paired terms encourages an adversarial stance rather than one of productive discourse. It’s not catchy so there’s probably better than this but, just as an example— “engage/ignore” could better signal to the user a neutral “do I want to bother with this person?”
I like friend and foe far more than engage and ignore. A foe isnt someone you ignore. Ignoring is what builds bubbles. A foe can often be right even if you disagree.
I'd prefer not to label things such that I'm justifying the label's negative potential by the disproportionately small "even if" range of positive ones.
