Since I don't have specific information on "Tamilgun group," I need to proceed carefully. The user might be referring to a lesser-known group. I should mention that the group isn't well-known but that Tamil Nadu has other groups that have been flagged for spreading misinformation. I should also highlight that any group promoting violence or secession is illegal and that users should refer to credible sources. It's important to stay neutral and not make assumptions but provide general advice on being cautious with online content.
