Wrong, PTI wasn't blocked because it didn't break any rules. PDF's did.
Literally no one cares what PDF posts in the wider world. PDF is a niche forum which is seen by those who have interest in Defence. No one else from any other county besides India and Pakistan even visits it. Every American,Israeli, etc here is here for DEFENCE matters. And believe me, that's not a lot of people. PDF has zero leverage in the world
Of course, India does. The trick is not to give them an excuse. PDF was banned because it broke the rules. Did Indians report it? Hell yes
Would you report IDF if you got the chance? Hell yes.
I speak as someone who's got a couple of fake Balochi accounts banned on Twitter by reporting them. If they break the rules, and you report en masse, they're banned. However, a couple were not banned because they didn't post any thing fake except their verbal diarrhea, which is not against Twitter Policy.
I have gotten a Hindu banned for saying all non-compliant Kashmiris should be shot
