WHAT IT DOES

What wa_group_remove_participants does on WA MCP

RISK

Why wa_group_remove_participants is rated Critical

Removing participants from a group is an irreversible action from the affected users' perspective — they lose access to the group conversation and must be re-invited manually. This constitutes a destructive operation with high blast radius if misused (e.g., mass-removing members from important groups), hence classified as Destructive with high severity.
