I seriously doubt that they would waste their time on this. They have much more powerful tools at their disposal.
1. Aatish Taseer: His OCI card (something like dual citizenship, but not quite) was cancelled. He claims he's been told not to even attempt to visit India ever again.
2. Rana Ayyub: she created a donation website and got clobbered with tax evasion.
3. Numerous NGOs: including Green Peace and Amnesty have had their licenses revoked.
There are many more such cases, but off the top of my head, these jumped out.
